The toy line, on the other hand, mostly ignores those additional components, resulting in massive scale discrepancies see above - Long Haulwho forms Devastator's right leg, is a massive Caterpillar B mining dump truck, which should make him considerably larger than Rampagea Caterpillar D9L bulldozer who forms the left leg. A panel in the " Time Wars " arc lptions GoldbugIronhideScattershotand Swoop all the same height. Group support for all other operators was finished in the. Amongst others, the concept was "popularized" by Michael J. Plugins should implement the IPlugin interface:. The coordinates of a hyperslab are specified with the.




You can download the latest version of Chart. If you download or clone the repository, you options call and put examples 4 scale run gulp build to generate the dist files. If this version is used and you require the use of putt time axis, Moment. This version should be used if you require time axes and want a single file to include, select this version.

Do not use this build sscale your application already includes Moment. If you do, Moment. To create a chart, we need to instantiate the Chart class. To do this, we need to pass in the node, jQuery instance, or 2d context of the canvas of where we want to draw the chart. Once you have the element or context, you're ready to instantiate a pre-defined chart-type or create your own!

The following example instantiates a bar chart showing the number of votes for scsle colors and the y-axis starting options call and put examples 4 scale 0. It's that easy to get started using Chart. From here you can explore the many options that can help you customise your charts with scales, tooltips, labels, colors, custom actions, and much more. There are many examples of Chart. These configuration options can be changed on a per chart basis by passing in an options object when creating the chart.

Alternatively, the global configuration can be changed which will be used by all charts created after that point. To display data, the chart must be passed a data object that contains all of the information needed by the chart. The data object can contain the following parameters To create a chart with configuration options, simply pass an object containing your configuration to the constructor.

In the example below, a line chart is created and configured to not be responsive. This concept was introduced in Chart. This way you can be as specific as you would like in your individual chart configuration, while still changing the defaults for all chart types where applicable. The global general options are defined in Chart. The defaults for each chart type are discussed in the documentation for that chart type.

The following example would set the hover mode to 'nearest' for all charts where this was not overridden by the chart type defaults or the options passed to the constructor on creation. There are 4 special global settings that can change all of the fonts on the chart. These options are in Chart. The following options are applicable to all charts. The can be set on the global configurationor they can be passed to the chart constructor.

The layout configuration is passed into the options. The global options for the chart layout is defined in Chart. The title configuration is passed into the options. The global options for examplee chart title is defined ccall Chart. The example below would enable a title of 'Custom Chart Title' on the chart that is created.

The legend configuration is passed into the options. The global options for the optikns legend is defined in Chart. Sscale legend label configuration is nested below the legend configuration using the labels key. Items passed to the legend onClick function are the ones returned from labels. These items must implement the following interface.

The following example will create a chart with the legend enabled and turn all of the text red in color. The tooltip configuration is passed into the options. The global options for the chart tooltips is defined in Chart. The tooltip label configuration is nested below the tooltip configuration using the callbacks key. The tooltip has the following callbacks for providing text. For all functions, 'this' will be the tooltip object created from the Chart. All functions are called with the same arguments: a tooltip item and the data object passed to the chart.

All functions must return either a string or an array of strings. Arrays of strings are treated as multiple lines of text. The hover configuration is passed into the options. The global hover configuration is at Chart. When configuring interaction with the graph via hover or tooltips, a number of different modes are available.

The following table details the modes and how they behave in conjunction with the intersect setting The following animation options are available. The global options for are defined in Chart. The onProgress and onComplete callbacks are useful for synchronizing an external draw to the chart animation. The callback is passed an object that implements the following interface. An example usage of these callbacks can be found on Github.

This sample displays a progress bar showing how far along the animation is. The animation object passed to the callbacks is of type Chart. The object has the following parameters. Options can be configured for four different types of elements: arc, lines, points, and rectangles. When set, these options apply to all objects of that type unless specifically overridden by the configuration attached to a dataset.

Arcs are used in the polar area, doughnut czll pie charts. They can be configured with the following options. The global arc options are stored in Chart. Line elements are used to represent the line in a line chart. The global line options are stored scals Chart. Point elements are used to represent the points in a line chart or a bubble chart. The global point options are stored in Chart. Rectangle elements are used to represent the bars in a bar chart.

The global rectangle options are stored in Chart. When supplying colors to Chart options, you can use a number of formats. You can specify the color as a string in hexadecimal, RGB, or HSL notations. If a color is needed, but not specified, Chart. This color is stored at Chart. It is initially set to 'rgba 0, 0, 0, 0. You will need to create this before passing to the chart, but using it you can achieve some interesting effects.

An alternative option is to pass a CanvasPattern object. For example, if you wanted to fill a dataset with a pattern from an image you could do the following. Using pattern fills acll data graphics can help viewers with vision deficiencies e. Using the Patternomaly library you sacle generate patterns to fill datasets. When creating a chart, you have the option to overlay different chart types on top of each other as separate datasets.

To do this, you must set a type for each dataset individually. You can create mixed chart types with bar and line chart types. A options call and put examples 4 scale chart is a way of plotting data points on a line. Often, it is used to show trend data, and the comparison of two data sets. The following options can be included in a line chart dataset to configure options for that specific dataset. If these are set to an array value, the first value applies to the first point, the second value to the second point, and so on.

The line chart usually requires an array of labels. This labels are shown on the X axis. There must be one label for each data point. More labels than datapoints are nad, in which case the line ends at the last data point. The data for scwle charts is broken up into an array of datasets. Each dataset has a opyions for the fill, a colour for the line and colours for the points and strokes of the points.

These colours nad strings just like CSS. You can use RGBA, RGB, HEX or HSL notation. The label key on each dataset is optional, and can be used when generating a scale for the chart. When spanGaps is set to true, the gaps between points in sparse datasets are filled in. By default, it is off. The data passed to the chart can be passed in two formats. The most common method is to pass the data array as an array of numbers. In this case, the data.

The alternate is used for sparse datasets. Data is sclae using an object containing x and y properties. This is used for scatter charts as documented below. Scatter line charts can be created by changing the X axis to a linear axis. To use a scatter chart, data must be passed as objects containing X and Y properties. The example below creates a scatter chart with 3 points. These are the customisation options specific to Line charts.

These options are merged with the global chart configuration optionsand form the options of the chart. You can override these for your Options call and put examples 4 scale instance by passing a member options into the Line method. For example, we could have a line chart display without an X axis by doing the following. The config merge is smart enough to handle arrays so that you do not need to specify all axis settings to change one thing. We can also change these defaults values for each Line type that is created, this object is available at Chart.

Stacked area charts can be created by setting the Y best forex broker for news trading ea to a stacked configuration. The following example would have stacked lines. The following options can be included in a bar chart dataset to configure options for that specific dataset. Some properties can be specified as an array. If these are set to an array value, the first value applies to the first bar, the second value to the second bar, and so on.

The bar chart has the a very similar data structure to the line chart, and has exampples array of datasets, each with colours and an array of data. We have an array of labels too for zcale. In the example, we are showing the same data as the previous line chart example. These are the customisation options specific to Bar charts. You can override these for your Chart instance by passing a metatrader latest version download jre argument into the Bar method as an object with the keys you want to override.

We can also change these defaults values for each Bar type that is created, this object is available at Chart. For horizontal bars, this object is available at Chart. The default options for horizontal bar charts are defined in Chart. The following shows the relationship between the bar percentage option and the category abd option.

The following options can be included in a radar chart dataset to configure options for that specific dataset. For a radar chart, to provide context of what each point means, we include an array of strings that show around each point in the chart. For the radar chart data, we have an array of datasets. Each of these is an object, with a fill colour, a stroke colour, a colour for the fill of each point, and a colour for the stroke of each point. We also have an array of data values.

These are the customisation options specific to Radar charts. You can override these for your Chart instance by passing a second argument into the Radar method as an object with the keys you want to override. For example, we could have a radar chart without a point for each on piece of data by doing the following: We can also change options call and put examples 4 scale defaults values for each Radar type that is created, this object is available at Chart.

Polar area charts are similar to pie charts, but each segment has the same angle - otions radius of the optiojs differs depending on the value. This type of chart is often useful when we want to show a comparison data similar to a pie chart, but also show a scale of values for context. The following options can be included in a polar area chart dataset to configure options for that specific dataset. Some properties are specified as arrays. The first value applies to the first bar, the second value to the second bar, and so on.

As you can see, for the chart data you pass in an array of objects, with a value and a colour. The value attribute should be a number, while the color attribute should be a string. Similar to CSS, for this string you can use HEX notation, RGB, RGBA or HSL. These are the customisation options specific to Polar Area charts. You can override these for your Chart instance by passing a second argument into the PolarArea method as an object with the keys you want to override.

Eamples can also change these defaults values for each PolarArea type that is created, this object is available at Chart. Pie and doughnut charts are probably the most commonly used charts there are. They are divided into segments, the arc of each segment shows the proportional value of each piece of data. Pie and doughnut charts are effectively the same class in Chart.

This equates what percentage of the inner should be cut out. This defaults to 0 for pie charts, and 50 for anv. They are also registered under two aliases in the Chart core. Other than their different default value, and different alias, they are exactly the same. For a pie chart, datasets need to contain an array of data points. The data points should be a number, Chart. You can also add an array of background colors.

The color attributes should be a string. You can override these for your Chart instance by passing a second argument into the Doughnut method as an object with the keys you want to override. For example, we could have a doughnut chart that animates by scaling out from the centre like so: We can also change these default values for each Doughnut type that is created, this object is available at Chart. Pie charts also have a clone of these defaults available to change at Chart.

A bubble chart is used to display three dimensions of data at the same time. The location of the bubble is determined by the first two dimensions and the corresponding horizontal and vertical axes. The third dimension is represented by the size of the individual bubbles. An example data object using these attributes is shown below. This example creates a single dataset with 2 different bubbles.

Data for the bubble chart is passed in the form of an object. The object must implement the following interface. It is important to note that the radius property, r is not scaled by the chart. It is the raw radius in pixels of the bubble that is drawn on the canvas. The bubble chart has no unique configuration options. To configure options common to all of the bubbles, the point element options are used.

We can also change the default values for the Bubble chart type. Doing so will give all bubble charts created after this point the new defaults. The default configuration for the bubble chart can be accessed at Chart. The grid line configuration is nested under the scale configuration in the gridLines key. It defines options for the grid lines that run perpendicular to the axis. Mt5 oanda forex scale label configuration is nested under the scale configuration in the scaleLabel key.

It defines options for the scale title. The tick configuration is nested under the scale configuration in the ticks key. It defines options for the tick marks that are generated by the axis. The callback method may be used for advanced tick customization. In the following example, every examplws of the Y axis would be displayed in scientific notation. If the callback returns null or undefined ezamples associated grid line will be hidden. The category scale will be familiar to those who have used v1.

Labels are drawn from one of the label arrays included in the chart data. Using both xLabels and yLabels together can create a chart that uses strings for both the X and Y axes. The linear scale is use to chart numerical data. It can be placed on either the x or y axis. The scatter chart type automatically configures a line chart to use one of these scales ane the x axis.

As the name suggests, linear interpolation is used to determine where a value lies on the axis. The following options are provided by the linear scale. They are all located in the ticks sub options. The following example creates a line chart with a vertical axis that goes from 0 to 5 in 0. The logarithmic scale is use to chart numerical data.

As the name suggests, logarithmic interpolation is used to determine where a value lies on the axis. The following options are provided by the logarithmic scale. The time scale is used to display times and dates. It can only be placed on the X axis. When building its ticks, it will automatically calculate the most comfortable exa,ples base on the size of the scale.

The ans options are provided by the time scale. They are all located in the time sub options. When providing data for the time scale, Chart. The following display formats are used to configure how different time units are formed dcale strings for the axis tick marks. For example, to set the display format for the 'quarter' unit to show the month and year, the following config would be passed to the chart constructor.

The following time measurements are supported. The names can be passed as strings to the time. For example, to create a chart with a time scale that always displayed units per month, the following config could be used. The radial linear scale is used specifically for the radar and polar area chart types. It overlays the chart area, rather than being positioned on ootions of the edges. The following options are used to configure angled lines that radiate from the center of the chart to the point labels.

They can be found in the angleLines sub options. Note that these options only apply if lineArc is false. The following options are used to configure the point labels that are cal on the perimeter of the scale. They can be found in the pointLabels sub options. The default configuration for a scale can be easily changed using the scale service. Pass in a partial configuration that will be merged with the current scale default cal.

For example, to set the minimum value of 0 for all linear scales, you would do the following. Any linear scales created after this time would now have a minimum of 0. For each chart, there are a set of global prototype methods on the shared ChartType which you may find useful. These are available on all charts created with Chart. Use this to destroy any chart instances that are created. This will clean up any references stored to the chart object within Chart.

This must be called before the canvas is reused for a new chart. Triggers anv update of the chart. This can be safely called after replacing the entire data object. This will update all scales, legends, and then re-render the chart. Reset the chart to it's state before the initial animation. A new animation can then be triggered using update. Triggers a redraw of all chart elements.

Note, this does not update elements for new data. Use this to stop any current animation loop. This will pause the chart during any current animation frame. Use this to manually resize the canvas element. This is run each time the canvas container is resized, but you can call this method manually if you change the size of the canvas nodes container element.

Will clear the chart canvas. Used extensively internally between animation frames, but exaamples might find it useful. Returns an HTML string of a legend for that chart. The legend is generated from the legendCallback in the options. Calling getElementAtEvent event on your Chart instance passing an argument of an event, or jQuery event, will return the single element at the event position. If there are multiple items within range, only the first is returned Looks for the element under the event point, then returns all elements at the same data index.

This is used internally for 'label' mode highlighting. Calling getElementsAtEvent event on your Chart instance passing an argument of an event, or jQuery event, will return the point elements that are at that the same position of that event. This functionality may be useful for implementing DOM based tooltips, or triggering custom behaviour in your application. Looks for the element under the event point, then returns all elements from that dataset.

This is used internally for 'dataset' mode highlighting Looks for sclae dataset that matches the current index and returns that metadata. This returned data has all of the metadata that is used to construct the chart. The data property of the metadata will contain information about each point, rectangle, etc. Extensive examples of usage are available in the Chart. Scales should always derive from Chart. Once you have created your scale class, you need to register it with the global chart object so that scals can be used.

A default config for the scale may be provided when registering the constructor. The first parameter to the register function is a string key that is used later to identify which scale type to use for a chart. Optionally, the following methods may also be overwritten, but an implementation is already provided by the Chart. Like scales, new controllers can be written as needed. Extending or replacing an existing controller type is easy.

Simply replace the constructor for one of the built in types with your own. The bar controller has a special property that you should be aware of. To correctly calculate the width of a bar, the controller must determine the number of datasets that map to bars. To do this, the forex szybki zyski controller attaches a property bar to the dataset optinos initialization. If you are creating a replacement or updated bar controller, you should do the same.

This will ensure that charts with regular bars and your new derived bars will work seamlessly. To register your plugin, simply call Chart. Plugins will be called at the following times Chart. Firstly, we need to ensure development dependencies are installed. With node and npm installed, after cloning the Chart. Please use the documentation that is available on chartjs. Thanks to BrowserStack for allowing our team to test on thousands of browsers.

Please report these on the GitHub page - at github. If you could include a link to a simple jsbin or similar to demonstrate the issue, that'd be really helpful. New contributions to the library are welcome, but we ask that you please follow these guidelines: Chart. There are many plugins that add additional functionality to Chart. Some particularly notable ones are listed here.

In addition, many plugins can be found on the Chart. Examles are many extensions which are available for use with popular frameworks. Selecting the Correct Build. Creating a Chart with Options.

Gets the item that is nearest to the point. The nearest item is determined based on the distance to optlons center of the chart item point, bar. If 2 or more items are at the same distance, the one with the smallest area is used. If intersect is true, this is only triggered when the mouse position intersects an item in the graph.

This is very useful for combo charts where points are hidden behind bars. Finds the first item that intersects the point and returns it. Finds item at the same index. If the intersect setting is true, the first intersecting item is used to determine the index in the data. If intersect false the nearest item is used to determine the index.

Finds items in the same dataset. Returns all items that would intersect based on the X coordinate of the position only. Would be useful for a vertical cursor implementation. Note that this only applies to cartesian charts. Returns all items that would intersect based on the Y coordinate of the position. This would be useful for a horizontal cursor implementation.

Options are 'circle', 'triangle', 'rect', 'rectRounded', 'rectRot', 'cross', 'crossRot', 'star', 'line', and 'dash'. If the option is an image, that image is drawn on the canvas using drawImage.

If false, the line is not drawn for this dataset. If true, lines will be drawn between points with no or null data. If true, the line is shown as a stepped line and 'lineTension' will be ignored. If false, the lines between points are not drawn. If true, NaN data does not break the line. Introduction A bar chart is a way of showing data as bars. It is sometimes used to profit from options trading strategies capital management trend data, and the comparison of multiple data sets side by side.

The data to plot as bars. The fill color of the bars. Border width of bar in pixels. Which edge to skip drawing the border for. Options are 'bottom', 'left', 'top', and 'right'. Bar background color when hovered. Bar border color when hovered. Border width of bar when hovered. The ID of the group to which this dataset belongs to when stacked, each group will be a separate stack. The bar chart officially supports only 1 x-axis but uses an array to keep the API consistent. Use a scatter chart if you need multiple x axes.

As defined in Scales. If true, show the scale. Id of the axis so that data can bind to it. If true, bars are stacked on the x-axis. Manually set width of each bar in pixels. If not set, the bars are sized automatically. Percent of the available width the space between the gridlines for small datasets for each data-point to use for the bars. Percent of the available width each puy should be within the category percentage.

If true, the bars for a particular data point fall between the grid lines. If false, the grid line will go right down the middle of the bars. If true, bars are stacked on the y-axis. Manually set height of each bar in pixels. Introduction A radar chart is a way of showing multiple data points and the variation between them. They are often useful for comparing the points of two or more different data sets. Options include 'circle', 'triangle', 'rect', 'rectRounded', 'rectRot', 'cross', 'crossRot', 'star', 'line', and 'dash'.

See Scales and Defaults for Radial Linear Scale. Options for optipns one scale used on the chart. Use this to style the ticks, labels, and grid lines. As defined in "Radial Linear". Options for all line elements used on the chart, as defined in the global elements, duplicated here to show Radar chart specific defaults. Tension exhibited by lines when calculating splineCurve. Setting to 0 creates straight lines.

If true, will animate scaling the calp. Returns labels for each the legend. Handles clicking an individual legend item. Generates the HTML legend via calls to generateLegend. Introduction Pie and doughnut charts are probably the most commonly used charts there are.

They are excellent at showing the relational proportions between data. The percentage of the chart that is cut out of the middle. Starting angle to draw arcs from. Sweep to allow arcs to cover. If true, will animate scaling the Doughnut from the centre. Returns a label for each item to be displayed on the legend.

Additional radius to add to data radius on hover. A built-in label auto-skip feature detects would-be overlapping ticks and labels and removes every nth label to keep things displaying normally.

Scale titles are supported. New scale types can be extended without writing an entirely new chart type. Common Configuration Every scale extends a core scale class with the following options:. Type of scale being employed. Custom scales can be created optoins registered with a string key. Options: "category""linear""logarithmic""time""radialLinear". If true, show the scale including gridlines, ticks, and labels. Position of the scale. The ID is used to link datasets and scale axes together.

This is especially needed if multi-axes charts are used. Callback called before the update process starts. Passed a single argument, the scale instance. Callback that runs before exakples are set. Callback that runs after dimensions are set. Callback that runs before data limits are determined. Callback that runs after data limits are determined. Callback that runs before ticks are created. Callback that runs after ticks are created.

Stroke width of grid lines. If true draw putt on the edge of the chart. If true, draw lines on the chart area inside the axis lines. This is useful when there are multiple axes and you need to control which grid lines are drawn. If true, draw lines beside the ticks in the axis area beside the chart.

Length in pixels that the grid lines will draw into the axis area. Stroke width of the grid line for the first index index 0. Stroke color calll the grid line for the first index index 0. If true, labels are shifted to be between grid lines. This is used in the bar chart. The text for the title. Font color for the scale title. Font family for the scale title, follows CSS font-family options. Font size for the scale title.

Turn it off to show all labels no matter what. Padding between the ticks on the horizontal axis when autoSkip is enabled. Note: Only applicable to horizontal scales. Returns the string representation of the tick value as it should be displayed on the chart.

See callback section below. If true, show the ticks. Font color for the tick labels. Font family for the tick labels, follows CSS font-family options. Font size for the tick labels. Font style for the tick labels, follows CSS font-style options i. Distance in pixels to offset the label from the centre point of the tick in the y direction for the x axis, and the x direction for the y axis. Note: this can cause labels at the edges to be cropped by the edge of the canvas. Maximum rotation for tick labels when rotating to condense labels.

Note: Rotation doesn't occur until necessary. Minimum rotation for tick labels. Flips tick labels around axis, displaying the labels inside the chart instead of outside. Note: Only applicable to vertical scales. Padding between the tick label and the axis. Reverses order of tick labels. The minimum item to display. Must be a value in the labels array.

The maximum item to display. Opyions defined minimum number for the scale, overrides minimum value from data. User options call and put examples 4 scale maximum number for the scale, overrides maximum value from data. Maximum options call and put examples 4 scale of ticks and gridlines to show. If not defined, it will limit to 11 ticks but will show all gridlines. User defined fixed step size for the scale. If set, the scale ticks will be enumerated by multiple of stepSize, having one tick per increment.

If not set, the ticks are labeled automatically using the nice numbers algorithm. See the example below. User defined maximum number for the scale, overrides maximum value except for if it is lower than the maximum value. User defined minimum number for the scale, overrides minimum value except for if it is options call and put examples 4 scale than the minimum value.

See Display Formats section below. If true and the unit is options call and put examples 4 scale to 'week', iso weekdays will be used. If defined, this will override sclae data maximum. If defined, this will override the data minimum. If defined as a string, it is interpreted as a custom format to be used by moment to parse the date. If this is a function, it must return a moment.

If defined, dates will be rounded to the start of this unit. See Time Units below for the allowed units. The moment js format string to use for the tooltip. If defined, will force the unit to be a certain type. Options call and put examples 4 scale Time Units section below for details. The number of units between grid lines. The minimum display format to be used for a time unit.

If true, circular arcs are used else straight lines are used. The former is used by the polar area chart and the latter by the radar chart. See the Angle Line Options section below for details. See the Point Label Options section below for details. See the Ticks exampples below for options. If true, angle lines are shown. Color of angled lines. Width of angled lines. Callback function to transform data label to axis label.

Font family to render. Font size in pixels. Font Style to use. Color of label backdrops. Horizontal padding of label backdrop. Vertical padding of label backdrop. If true, draw a background behind the tick labels. Prototype Methods For each chart, there are a set of lut prototype methods on the shared ChartType which you may find useful. If there are multiple items within range, only the first is returned. This is used internally for 'dataset' mode highlighting. External Tooltips You can enable custom tooltips in the global or chart configuration like so:.

Writing New Scale Types Starting with Chart. To use the new scale, simply pass in the string key to the config when creating a chart. Scqle Properties Scale instances are given the following properties during the fitting process. Like css, this is outside the bounding box. Scale Interface To work with Chart. The data object can be accessed as this. The default implementation simply calls this. The default implementation will only rotate labels if the scale is horizontal.

Scales should endeavour to be as efficient as possible with canvas space. This is used already for calculating the best label rotation. It must be an object containing 2 properties: width and height. This is the rectangle that lines, bars, etc will be drawn in. It may be used, for example, to draw grid lines. Scale base class also has some utility functions that you may find useful. Writing New Chart Types Chart. Dataset Controller Interface Dataset controllers must implement the following interface.

Store elements in an array exammples the dataset as dataset. See the implementation of draw in any of the provided controllers to see how this puy be used. The following methods examplse optionally be overridden by derived dataset controllers. The default implementation handles options call and put examples 4 scale number of data points changing and creating elements appropriately. Extending Existing Chart Types Extending or replacing an existing controller type is easy.

The built in controller types sacle. Bar Controller The bar controller has a special property that you should be aware of. Creating Plugins Starting with v2. Plugins will be called at the following times. After the chart scales have calculated. Start of datasets update. End of datasets update. End of update before render occurs. Before an animation is started. When an event occurs on the canvas mousemove, click, etc. This requires the options.

Plugins should implement the Wxamples interface:. It is only called once, even if the animation will run for a number of frames. Use beforeDraw or afterDraw. This will install the local development dependencies for Chart. Now, we can run the gulp build task. Previous versions Version 2 has a completely different API than earlier versions.

Most earlier version options have current equivalents or are the same. Please note - documentation for previous versions are available on the GitHub repo. Contributing New contributions pput the library are welcome, but we ask that you please follow these guidelines:. Use tabs for indentation, not spaces. Check that your code will pass eslint code standards, gulp lint will run this for you.

Check that your code will pass tests, gulp test will run tests scalf you. Keep pull Buy stock online without a broker minimum deposit concise, and document new functionality in the relevant. Consider whether your changes are useful for all users, or if creating a Chart. Charting Library Comparison Library Features. Extendable to Custom Charts. See the documentation for each chart type to determine the valid options that can be attached to the dataset ["mousemove", "mouseout", "click", "touchstart", "touchmove", "touchend"] Called if the event is of type 'mouseup' or 'click'.

Called in the context of the chart and passed the event and an array of active elements Function to generate a legend. Receives 2 parameters, a Legend Item and the chart data Label style will match corresponding point style size is based on fontSize, boxWidth is not used in this case. Puf Interaction Modes for details if true, the tooltip mode applies only when the mouse position intersects with an element.

See Interaction Modes for details Called when any of the events fire. Called in the context of the chart and passed the event and an array of active elements options call and put examples 4 scale, points, etc Gets the item that is nearest to the point. Note that this only applies to cartesian charts Returns all items that would intersect based on the Y coordinate of the position.

Passed the same arguments as onProgress Default line cap style. See MDN Default line dash. See MDN Default line dash offset. See MDN Default line join style. See MDN If true, the fill is assumed to be to zero. If falseno fill is added Default skipped excluded border for rectangle. Can be one of bottomlefttopright Algorithm used to interpolate a smooth curve from the discrete data points. See MDN Length and spacing of dashes. See MDN Offset for line dashes.

See MDN Line joint style. See MDN The style of point. Options are 'bottom', 'left', 'top', and 'right' The ID of the group to which this dataset belongs to when stacked, each group will be a separate stack Label's hover mode. Read More Optinos of the available znd each bar should be within the category percentage. Read More If true, the bars for a particular data point fall between the grid lines. Options include 'circle', 'triangle', 'rect', 'rectRounded', 'rectRot', 'cross', 'crossRot', 'star', 'line', and 'dash' See Scales and Defaults for Radial Linear Scale Options for the one scale used on the chart.

See Scales and Defaults for Radial Linear Scale Type of scale being employed. Options: "category""linear""logarithmic""time""radialLinear" If true, show the scale including gridlines, ticks, and labels. See MDN If true, draw lines on the chart area inside the axis lines. This is useful when there are multiple axes and you need to control which grid lines are drawn Font style for the scale title, follows CSS font-style options i. Turn it off to show all labels no matter what Wxamples between the ticks on the horizontal axis when autoSkip is enabled.

Note: this can cause labels at the edges to be cropped by the edge of the canvas Maximum rotation for tick labels when rotating to condense labels.
