Pie chart

Introduction

Note: PatternFly React charts live in its own package at @patternfly/react-charts!

PatternFly React charts are based on the Victory chart library, along with additional functionality, custom components, and theming for PatternFly. This provides a collection of React based components you can use to build PatternFly patterns with consistent markup, styling, and behavior.

Examples

Basic with right aligned legend

Multi-color (ordered) with bottom aligned legend

Custom color scale

This demonstrates how to apply a custom color scale.

Documentation

Tips

See Victory's FAQ
For single data points or zero values, you may want to set the domain prop
ChartLegend may be used as a standalone component, instead of using legendData

Note

Currently, the generated documentation below is not able to resolve type definitions from Victory imports. For the components used in the examples above, Victory pass-thru props are also documented here:

Props

ChartPie

ChartPie renders a dataset as a pie chart. See https://github.com/FormidableLabs/victory/blob/main/packages/victory-pie/src/index.d.ts
*required
Name	Type	Default	Description
allowTooltip	boolean	true	Specifies the tooltip capability of the container component. A value of true allows the chart to add a ChartTooltip component to the labelComponent property. This is a shortcut to display tooltips when the labels property is also provided.
animate	boolean \| object		The animate prop specifies props for VictoryAnimation to use. The animate prop should also be used to specify enter and exit transition configurations with the `onExit` and `onEnter` namespaces respectively. @example {duration: 500, onExit: () => {}, onEnter: {duration: 500, before: () => ({y: 0})})}
ariaDesc	string		The ariaDesc prop specifies the description of the chart/SVG to assist with accessibility for screen readers. Note: Overridden by the desc prop of containerComponent
ariaTitle	string		The ariaTitle prop specifies the title to be applied to the SVG to assist accessibility for screen readers. Note: Overridden by the title prop of containerComponent
categories	string[] \| { x: string[], y: string[] }		The categories prop specifies how categorical data for a chart should be ordered. This prop should be given as an array of string values, or an object with these arrays of values specified for x and y. If this prop is not set, categorical data will be plotted in the order it was given in the data array @example ["dogs", "cats", "mice"]
colorScale	string[]		The colorScale prop is an optional prop that defines the color scale the pie will be created on. This prop should be given as an array of CSS colors, or as a string corresponding to one of the built in color scales. ChartPie will automatically assign values from this color scale to the pie slices unless colors are explicitly provided in the data object
constrainToVisibleArea	boolean	false	The constrainToVisibleArea prop determines whether to coerce tooltips so that they fit within the visible area of the chart. When this prop is set to true, tooltip pointers will still point to the correct data point, but the center of the tooltip will be shifted to fit within the overall width and height of the svg Victory renders.
containerComponent	React.ReactElement<any>	<ChartContainer />	The containerComponent prop takes an entire component which will be used to create a container element for standalone charts. The new element created from the passed containerComponent wil be provided with these props from ChartPie: height, width, children (the chart itself) and style. Props that are not provided by the child chart component include title and desc, both of which are intended to add accessibility to Victory components. The more descriptive these props are, the more accessible your data will be for people using screen readers. Any of these props may be overridden by passing in props to the supplied component, or modified or ignored within the custom component itself. If a dataComponent is not provided, ChartPie will use the default ChartContainer component. @example <ChartContainer title="Chart of Dog Breeds" desc="This chart shows ..." />
cornerRadius	number \| Function		Set the cornerRadius for every dataComponent (Slice by default) within ChartPie
data	any[]		The data prop specifies the data to be plotted, where data X-value is the slice label (string or number), and Y-value is the corresponding number value represented by the slice Data should be in the form of an array of data points. Each data point may be any format you wish (depending on the `x` and `y` accessor props), but by default, an object with x and y properties is expected. @example [{x: 1, y: 2}, {x: 2, y: 3}], [[1, 2], [2, 3]], [[{x: "a", y: 1}, {x: "b", y: 2}], [{x: "a", y: 2}, {x: "b", y: 3}]]
dataComponent	React.ReactElement<any>		The dataComponent prop takes an entire, HTML-complete data component which will be used to create slices for each datum in the pie chart. The new element created from the passed dataComponent will have the property datum set by the pie chart for the point it renders; properties style and pathFunction calculated by ChartPie; an index property set corresponding to the location of the datum in the data provided to the pie; events bound to the ChartPie; and the d3 compatible slice object. If a dataComponent is not provided, ChartPie's Slice component will be used.
endAngle	number		The overall end angle of the pie in degrees. This prop is used in conjunction with startAngle to create a pie that spans only a segment of a circle.
eventKey	number \| string \| Function		Similar to data accessor props `x` and `y`, this prop may be used to functionally assign eventKeys to data
events	object[]		The event prop takes an array of event objects. Event objects are composed of a target, an eventKey, and eventHandlers. Targets may be any valid style namespace for a given component, so "data" and "labels" are all valid targets for ChartPie events. The eventKey may optionally be used to select a single element by index rather than an entire set. The eventHandlers object should be given as an object whose keys are standard event names (i.e. onClick) and whose values are event callbacks. The return value of an event handler is used to modify elemnts. The return value should be given as an object or an array of objects with optional target and eventKey keys, and a mutation key whose value is a function. The target and eventKey keys will default to those corresponding to the element the event handler was attached to. The mutation function will be called with the calculated props for the individual selected element (i.e. a single bar), and the object returned from the mutation function will override the props of the selected element via object assignment. @example events={[ { target: "data", eventKey: 1, eventHandlers: { onClick: () => { return [ { eventKey: 2, mutation: (props) => { return {style: merge({}, props.style, {fill: "orange"})}; } }, { eventKey: 2, target: "labels", mutation: () => { return {text: "hey"}; } } ]; } } } ]}
externalEventMutations	object[]		ChartPie uses the standard externalEventMutations prop.
groupComponent	React.ReactElement<any>		The groupComponent prop takes an entire component which will be used to create group elements for use within container elements. This prop defaults to a <g> tag on web, and a react-native-svg <G> tag on mobile
hasPatterns	boolean \| boolean[]		The hasPatterns prop is an optional prop that indicates whether a pattern is shown for a chart. SVG patterns are dynamically generated (unique to each chart) in order to apply colors from the selected color theme or custom color scale. Those generated patterns are applied in a specific order (via a URL), similar to the color theme ordering defined by PatternFly. If the multi-color theme was in use; for example, colorized patterns would be displayed in that same order. Create custom patterns via the patternScale prop. Note: Not all components are supported; for example, ChartLine, ChartBullet, ChartThreshold, etc. @example hasPatterns={ true } @example hasPatterns={[ true, true, false ]}
height	number	theme.pie.height	Specifies the height the svg viewBox of the chart container. This value should be given as a number of pixels. Because Victory renders responsive containers, the width and height props do not determine the width and height of the chart in number of pixels, but instead define an aspect ratio for the chart. The exact number of pixels will depend on the size of the container the chart is rendered into. Note: When adding a legend, height (the overall SVG height) may need to be larger than pieHeight (the pie size) in order to accommodate the extra legend. By default, pieHeight is the min. of either height or width. This covers most use cases in order to accommodate legends within the same SVG. However, pieHeight (not height) may need to be set in order to adjust the pie height. Typically, the parent container is set to the same width in order to maintain the aspect ratio.
innerRadius	number \| Function		When creating a donut chart, this prop determines the number of pixels between the center of the chart and the inner edge. When this prop is set to zero a regular pie chart is rendered.
labelComponent	React.ReactElement<any>	allowTooltip ? ( <ChartTooltip constrainToVisibleArea={constrainToVisibleArea} theme={theme} /> ) : undefined	The labelComponent prop takes in an entire label component which will be used to create a label for the area. The new element created from the passed labelComponent will be supplied with the following properties: x, y, index, data, verticalAnchor, textAnchor, angle, style, text, and events. any of these props may be overridden by passing in props to the supplied component, or modified or ignored within the custom component itself. If labelComponent is omitted, a new ChartLabel will be created with props described above. This labelComponent prop should be used to provide a series label for ChartPie. If individual labels are required for each data point, they should be created by composing ChartPie with VictoryScatter
labelPosition	string \| Function		The labelPosition prop specifies the angular position of each label relative to its corresponding slice. This prop should be given as "startAngle", "endAngle", "centroid", or as a function that returns one of these values. When this prop is not given, the label will be positioned at the centroid of each slice.
labelRadius	number \| Function		The labelRadius prop defines the radius of the arc that will be used for positioning each slice label. If this prop is not set, the label radius will default to the radius of the pie + label padding.
labels	string[] \| number[] \| ((data: any) => string \| number \| null)		The labels prop defines labels that will appear above each bar in your chart. This prop should be given as an array of values or as a function of data. If given as an array, the number of elements in the array should be equal to the length of the data array. Labels may also be added directly to the data object like data={[{x: 1, y: 1, label: "first"}]}. @example ["spring", "summer", "fall", "winter"], (datum) => datum.title
legendAllowWrapBeta	boolean \| ((extraHeight: number) => void)	false	Allows legend items to wrap onto the next line if the chart is not wide enough. Note that the chart's SVG height and width are 100% by default, so it can be responsive itself. However, if you define the height and width of the chart's parent container, you must accommodate for extra legend height due to legend items wrapping onto the next line. When the height of the chart's parent container is too small, some legend items may not be visible. Alternatively, a callback function may be provided, which will be called after the legend's itemsPerRow property has been calculated. The value provided can be used to increase the chart's parent container height as legend items wrap onto the next line. If no adjustment is necessary, the value will be zero. Note: This is overridden by the legendItemsPerRow property
legendComponent	React.ReactElement<any>	<ChartLegend />	The legend component to render with chart. Note: Use legendData so the legend width can be calculated and positioned properly. Default legend properties may be applied
legendData	{ name?: string; symbol?: { fill?: string; type?: string; }; }[]		Specify data via the data prop. ChartLegend expects data as an array of objects with name (required), symbol, and labels properties. The data prop must be given as an array. @example legendData={[{ name: `GBps capacity - 45%` }, { name: 'Unused' }]}
legendDirectionBeta	'ltr' \| 'rtl'	'ltr'	Text direction of the legend labels.
legendOrientation	'horizontal' \| 'vertical'	theme.legend.orientation	The orientation prop takes a string that defines whether legend data are displayed in a row or column. When orientation is "horizontal", legend items will be displayed in a single row. When orientation is "vertical", legend items will be displayed in a single column. Line and text-wrapping is not currently supported, so "vertical" orientation is both the default setting and recommended for displaying many series of data.
legendPosition	'bottom' \| 'right'	ChartCommonStyles.legend.position	The legend position relation to the pie chart. Valid values are 'bottom' and 'right' Note: When adding a legend, padding may need to be adjusted in order to accommodate the extra legend. In some cases, the legend may not be visible until enough padding is applied.
name	string		The name prop is typically used to reference a component instance when defining shared events. However, this optional prop may also be applied to child elements as an ID prefix. This is a workaround to ensure Victory based components output unique IDs when multiple charts appear in a page.
origin	{ x: number, y: number }		Victory components will pass an origin prop is to define the center point in svg coordinates for polar charts. Note: It will not typically be necessary to set an origin prop manually
padAngle	number \| Function		The padAngle prop determines the amount of separation between adjacent data slices in number of degrees
padding	number \| { top: number, bottom: number, left: number, right: number }		The padding props specifies the amount of padding in number of pixels between the edge of the chart and any rendered child components. This prop can be given as a number or as an object with padding specified for top, bottom, left and right.
patternScale	string[]		The patternScale prop is an optional prop that defines patterns to apply, where applicable. This prop should be given as a string array of pattern URLs. Patterns will be assigned to children by index and will repeat when there are more children than patterns in the provided patternScale. Use null to omit the pattern for a given index. Note: Not all components are supported; for example, ChartLine, ChartBullet, ChartThreshold, etc. @example patternScale={[ 'url("#pattern1")', 'url("#pattern2")', null ]}
radius	number \| Function		Specifies the radius of the chart. If this property is not provided it is computed from width, height, and padding props
sortKey	number \| string \| Function \| string[]		Use the sortKey prop to indicate how data should be sorted. This prop is given directly to the lodash sortBy function to be executed on the final dataset.
sortOrder	string		The sortOrder prop specifies whether sorted data should be returned in 'ascending' or 'descending' order.
standalone	boolean	true	The standalone prop determines whether the component will render a standalone svg or a <g> tag that will be included in an external svg. Set standalone to false to compose ChartPie with other components within an enclosing <svg> tag.
startAngle	number		The overall start angle of the pie in degrees. This prop is used in conjunction with endAngle to create a pie that spans only a segment of a circle.
style	{ parent: object, data: object, labels: object }		The style prop specifies styles for your pie. ChartPie relies on Radium, so valid Radium style objects should work for this prop. Height, width, and padding should be specified via the height, width, and padding props. @example {data: {stroke: "black"}, label: {fontSize: 10}}
theme	object	getTheme(themeColor)	The theme prop takes a style object with nested data, labels, and parent objects. You can create this object yourself, or you can use a theme provided by When using ChartPie as a solo component, implement the theme directly on ChartPie. If you are wrapping ChartPie in ChartChart or ChartGroup, please call the theme on the outermost wrapper component instead.
themeColor	string		Specifies the theme color. Valid values are 'blue', 'green', 'multi', etc. Note: Not compatible with theme prop @example themeColor={ChartThemeColor.blue}
width	number	theme.pie.width	Specifies the width of the svg viewBox of the chart container. This value should be given as a number of pixels. Because Victory renders responsive containers, the width and height props do not determine the width and height of the chart in number of pixels, but instead define an aspect ratio for the chart. The exact number of pixels will depend on the size of the container the chart is rendered into. Typically, the parent container is set to the same width in order to maintain the aspect ratio.
x	number \| string \| Function \| string[]		The x prop specifies how to access the X value of each data point. If given as a function, it will be run on each data point, and returned value will be used. If given as an integer, it will be used as an array index for array-type data points. If given as a string, it will be used as a property key for object-type data points. If given as an array of strings, or a string containing dots or brackets, it will be used as a nested object property path (for details see Lodash docs for _.get). If `null` or `undefined`, the data value will be used as is (identity function/pass-through). @example 0, 'x', 'x.value.nested.1.thing', 'x[2].also.nested', null, d => Math.sin(d)
y	number \| string \| Function \| string[]		The y prop specifies how to access the Y value of each data point. If given as a function, it will be run on each data point, and returned value will be used. If given as an integer, it will be used as an array index for array-type data points. If given as a string, it will be used as a property key for object-type data points. If given as an array of strings, or a string containing dots or brackets, it will be used as a nested object property path (for details see Lodash docs for _.get). If `null` or `undefined`, the data value will be used as is (identity function/pass-through). @example 0, 'y', 'y.value.nested.1.thing', 'y[2].also.nested', null, d => Math.sin(d)
