⚙️Properties

❕ Required props

Data prop

Chart data. An array of objects (Array<TDataItem>) with properties described below:

NameTypeDefaultRequiredDescription
colorstringundefined-The color of the chart segment. Must be CSS type 'color'. Default generated automatically
ordernumberundefined-Order of segments in a chart. Default generated automatically
segmentIdstringundefined-The unique ID of the chart segment. Default generated automatically
valuenumberundefined+Segment value

parentRef prop - Required if the size prop is not passed

NameTypeDefaultDescription
parentRefRefObjectundefinedRef to the parent HTMLElement

size prop - Required if the parentRef prop is not passed

NameTypeDefaultDescription
sizenumberundefinedChart size

❔ Optional props

NameTypeDefaultDescription
animationSpeednumber200The speed (in milliseconds) of the animation when the values of the chart element change
chartCenterSizenumberundefinedThe name of the chart center class. The "chart center" is the svg element above the main chart. It's kind of like a text background. "Chart center" will not be shown without "chartCenterSize" parameter. Don't use it if you just want to create a donut-type chart, it's better to pass the parameter "donutThickness" instead
childrenReactNode | string | numberundefined"Children" to render in the center of the chart.
classNamestringundefinedMain className
classNamesstringundefinedChart elements classNames
colorsstringundefinedChart elements colors
resizeReRenderDebounceTimenumber50Prevents unnecessary re-renders. Debounce is disabled when 'resizeReRenderDebounceTime' = 0 or when the value of the "size" property is set
donutThicknessnumberundefinedThe thickness of the donut segments. You should pass this prop if you want to create a donut chart.
fontSizenumberundefinedThe font size. By default, it calculates automatically to fit the size of the whole chart (outer radius) if the chart is "Pie" type. If the chart is "Donut" type this param calculates automatically to fit the size of "donut hole" (inner radius).
gapnumberundefinedGap between segments
hoverScaleRationumber1.05The ratio of the "scale" of the segment when it's hovered, selected or focused
isScaleOnHoverbooleanTRUEEnables or disables "scale" of the segment when it's hovered, active or focused
isSelectOnClickbooleanTRUEEnables or disables segment selection on click on it
isSelectOnKeyEnterDownbooleanTRUEEnables or disables segment selection on "enter" key press on it
isSelectedValueShownInCenterbooleanTRUEEnables or disables the display of the value of the selected segment in the center of the chart
maxSizenumberundefinedChart maximum size.
minSizenumberundefinedChart minimum size
stylesHoveredSegmentCSSPropertiesundefinedYour own styles for hovered, selected or focused segments
onSegmentClick(segmentId: string) => voidundefinedCallback for segment "onClick" event
onSegmentKeyEnterDown(segmentId: string) => voidundefinedCallback for segment "onKeydown" event. Fires only for the "enter" key
selectedstringundefinedSelected segment ID. In most cases you don't need it. But if you want to control this state manually - welcome =)
widthSegmentFocusedOutlinenumber4The width of the "outline" (stroke) of the focused segment. By default, it automatically resizes based on chart size and has a ratio of 0.0066. This means that this stroke width = <chart_size> * 0.0066
tabIndexnumber0Enables or disables chart navigation with a "tab". Default - accessible - you can navigate the chart with the keyboard ("tab" button) And in most cases there is no reason to change it.
textstringundefinedText to show in the center of the chart. By default, it shows the total value of the provided "data" or the value of the selected segment or the value of the focused segment
📌 Notes

You can choose whether you want to resize the chart based on the "parent" size or if you want to set the size manually. If you need a resizable chart, you must be sure that the parent container does not have zero width and height. If you want to set the size manually just add the size property

The Chart has a lot of flexible settings. You can check them out above.

📌 Additional info about classNames & colors props
classNames prop - Chart elements classNames. An object with following props:
NameTypeDefaultDescription
chartBackgroundstringundefinedChart background className. Background - svg element the same size as the chart, and it is rendered if 'colorSegmentsBackground' property is provided
chartCenterstringundefinedCenter circle (donut hole) className
chartSegmentstringundefinedChart segment className
chartSegmentsBackgroundstringundefinedChart segment background className
childrenstringundefinedChart children className
svgGroupSegmentsstringundefinedChart segments group element className
svgGroupSegmentsBackgroundstringundefinedChart segments group element className. This background is another element under the chart segments group element
svgGroupTextstringundefinedChart text group element className
svgObjectTextstringundefinedChart text element className. is something like element-wrapper for the text container
textstringundefinedText container className
colors prop - Chart elements colors. An object with following props:
NameTypeDefaultDescription
chartBackgroundstringundefinedColor of the chart background. Background is svg element same size with chart. Not renders if this param was not passed
chartCenterstring#ffffffCenter circle (donut hole) color
segmentFocusedOutlinestring#287bc8Focused segments outline (stroke) color
segmentsBackgroundstringundefinedBackground color of the chart segments background element. Segments background is an svg element same size with chart. 1. Not renders if this param was not passed 2. This is not the segments background. This is background of element under all segments. Sounds complicated, I know... But it needed if you want to create a chart with gaps between segments and to color this space (gap) between segments. When the chart is Pie type this param works same like 'colorChartBackground' prop, but if chart is Donut type then current param will color only the circle under the segments but not the whole chart
textstringundefinedThe color of the text. By default, it will be same color with selected segment (if any segment is selected) or same color with the biggest value in the "data" array.

Make sure the colors provided to the "PieDonutChart" meet the following requirements: Color must be only HEX string and must be

  • 7-characters starts with "#" symbol - '#ffffff'
  • or 6-characters without "#" symbol - 'ffffff'
  • or 4-characters starts with "#" symbol - '#fff'
  • or 3-characters without "#" symbol - fff

🚀️ Example

import PieDonutChart, { DataItem } from '@garvae/react-pie-donut-chart';
import React from 'react';

const DATA: DataItem[] = [
    {
        color: '#287BC8',
        id: '001',
        order: 1,
        value: 10,
    },
    {
        color: '#D64045',
        id: '002',
        order: 2,
        value: 40,
    },
    {
        color: '#daf6ec',
        id: '003',
        order: 3,
        value: 30,
    },
    {
        color: '#9ED8DB',
        id: '004',
        order: 4,
        value: 20,

    {
        color: '#2B2D42',
        id: '005',
        order: 5,
        value: 50,
    },
];

// "Pie" type chart variant with "parentRef" prop (auto-resize)
const ChartPieAutoResize = () => {
    const ref = React.useRef<HTMLDivElement>(null);

    return (
        <div
            ref={ref}
            style={{ height: '300px', width: '300px' }}
        >
            <PieDonutChart
                data={DATA}
                parentRef={ref}
            />
        </div>
    );
};

// "Pie" type chart variant with "size" prop (no auto-resize)
const ChartPieWithFixedSize = () => {
    return (
        <PieDonutChart
            data={DATA}
            size={300}
        />
    );
};

// "Donut" type chart variant with "size" prop (no auto-resize)
const ChartDonutWithFixedSize = () => {
    return (
        <PieDonutChart
            data={DATA}
            gap={10}
            size={300}
        />
