React Chart - Access a Series Using the API

The Chart exposes the following methods for accessing a series. All of them return one or several objects whose fields and methods are described in the Series section of the API reference.

getAllSeries()
Gets all series of the Chart.

App.js


import React from 'react';
import Chart from 'devextreme-react/chart';
 
class App extends React.Component {
    constructor(props) {
        super(props);
        this.chartRef = React.createRef();
    }
    render() {
        return (
            <Chart ref={this.chartRef}></Chart>
        );
    }
    get chart() {
        return this.chartRef.current.instance();
    }
    getAllSeries () {
        return this.chart.getAllSeries();
    }
}
 
export default App;

getSeriesByName(seriesName)
Gets a series by its name.

App.js


import React from 'react';
import Chart from 'devextreme-react/chart';
 
class App extends React.Component {
    constructor(props) {
        super(props);
        this.chartRef = React.createRef();
    }
    render() {
        return (
            <Chart ref={this.chartRef}></Chart>
        );
    }
    get chart() {
        return this.chartRef.current.instance();
    }
    getSeriesByName (seriesName) {
        return this.chart.getSeriesByName(seriesName);
    }
}
 
export default App;

getSeriesByPos(seriesIndex)
Gets a series by its index in the series array. The index is zero-based.

App.js


import React from 'react';
import Chart from 'devextreme-react/chart';
 
class App extends React.Component {
    constructor(props) {
        super(props);
        this.chartRef = React.createRef();
    }
    render() {
        return (
            <Chart ref={this.chartRef}></Chart>
        );
    }
    get chart() {
        return this.chartRef.current.instance();
    }
    getSeriesByPos(seriesIndex) {
        return this.chart.getSeriesByPos(seriesIndex);
    }
}
 
export default App;

Apart from the API methods, you can access a series in the event handlers. For example, the onSeriesClick event handler gets the clicked series in the argument.

App.js


import React from 'react';
import Chart from 'devextreme-react/chart';
 
class App extends React.Component {
    render() {
        return (
            <Chart onSeriesClick={onSeriesClick}>
            </Chart>
        );
    }
}
 
function onSeriesClick (e) {
    const series = e.target;
    // ...
}
 
export default App;

Once you get the series, you can access its child points. For further information, refer to the Access a Series Point Using the API topic.
