jQuery PieChart - Overview
A series is a collection of related data points. The most important characteristic of a series is its type. The PieChart provides Pie and Doughnut series types; the only difference between them is the Doughnut has a blank center.
The Pie series type is used by default, but you can change it to Doughnut using the type property.
jQuery
$(function() {
$("#pieChartContainer").dxPieChart({
type: "doughnut" // or "donut"
});
});Angular
<dx-pie-chart
type="doughnut"> <!-- or "donut" -->
</dx-pie-chart>
import { DxPieChartModule } from "devextreme-angular";
// ...
export class AppComponent {
// ...
}
@NgModule({
imports: [
// ...
DxPieChartModule
],
// ...
})Vue
<template>
<DxPieChart ...
type="doughnut"> <!-- or "donut" -->
</DxPieChart>
</template>
<script>
import DxPieChart from 'devextreme-vue/pie-chart';
export default {
components: {
DxPieChart
}
}
</script>React
import React from 'react';
import PieChart from 'devextreme-react/pie-chart';
const App = () => {
return (
<PieChart ...
type="doughnut"> {/* or "donut" */}
</PieChart>
);
};
export default App;Use the series property to configure a series. Pass an object to this property if you have only one series, or an array of objects when you have multiple series. In the latter case, you can also specify settings common for all series in the commonSeriesSettings object, for example:
jQuery
$(function() {
$("#pieChartContainer").dxPieChart({
commonSeriesSettings: {
argumentField: "year"
},
series: [{
valueField: "men"
}, {
valueField: "women"
}]
});
});Angular
<dx-pie-chart>
<dxo-common-series-settings
argumentField="year">
</dxo-common-series-settings>
<dxi-series valueField="men"></dxi-series>
<dxi-series valueField="women"></dxi-series>
</dx-pie-chart>
import { DxPieChartModule } from "devextreme-angular";
// ...
export class AppComponent {
// ...
}
@NgModule({
imports: [
// ...
DxPieChartModule
],
// ...
})Vue
<template>
<DxPieChart ... >
<DxCommonSeriesSettings
argument-field="year"
/>
<DxSeries value-field="men" />
<DxSeries value-field="women" />
</DxPieChart>
</template>
<script>
import DxPieChart, {
DxCommonSeriesSettings,
DxSeries
} from 'devextreme-vue/pie-chart';
export default {
components: {
DxPieChart,
DxCommonSeriesSettings,
DxSeries
}
}
</script>React
import React from 'react';
import PieChart, {
CommonSeriesSettings,
Series
} from 'devextreme-react/pie-chart';
const App = () => {
return (
<PieChart ... >
<CommonSeriesSettings
argumentField="year"
/>
<Series valueField="men" />
<Series valueField="women" />
</PieChart>
);
};
export default App;Settings specified for a series apply to all its points. If you need to customize an individual point, assign a function to the customizePoint property. This function must return an object with properties for the point that you want to customize.
jQuery
$(function() {
$("#pieChartContainer").dxPieChart({
series: {
color: "blue"
},
// All series points with the value more than 100 turn red
// Other series points remain blue
customizePoint: function (pointInfo) {
return pointInfo.value > 100 ? { color: "red" } : { }
}
});
});Angular
<dx-pie-chart
[customizePoint]="customizePoint">
<dxi-series color="blue"></dxi-series>
</dx-pie-chart>
import { DxPieChartModule } from "devextreme-angular";
// ...
export class AppComponent {
// All series points with the value more than 100 turn red
// Other series points remain blue
customizePoint (pointInfo: any) {
return pointInfo.value > 100 ? { color: 'red' } : { }
};
}
