DevExtreme Angular - 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.

    jQuery
    JavaScript
    var seriesCollection = $("#chartContainer").dxChart("getAllSeries");
    Angular
    TypeScript
    import { ..., ViewChild } from "@angular/core";
import { DxChartModule, DxChartComponent } from "devextreme-angular";
// ...
export class AppComponent {
    @ViewChild(DxChartComponent, { static: false }) chart: DxChartComponent;
    // Prior to Angular 8
    // @ViewChild(DxChartComponent) chart: DxChartComponent;
    seriesCollection: any = [];
    getAllSeries() {
        this.seriesCollection = this.chart.instance.getAllSeries();
    }
}
@NgModule({
    imports: [
        // ...
        DxChartModule
    ],
    // ...
})

  • getSeriesByName(seriesName)
    Gets a series by its name.

    jQuery
    JavaScript
    var series = $("#chartContainer").dxChart("getSeriesByName", "Series 1");
    Angular
    TypeScript
    import { ..., ViewChild } from "@angular/core";
import { DxChartModule, DxChartComponent } from "devextreme-angular";
// ...
export class AppComponent {
    @ViewChild(DxChartComponent, { static: false }) chart: DxChartComponent;
    // Prior to Angular 8
    // @ViewChild(DxChartComponent) chart: DxChartComponent;
    series: any = {};
    getSeries() {
        this.series = this.chart.instance.getSeriesByName("Series 1");
    }
}
@NgModule({
    imports: [
        // ...
        DxChartModule
    ],
    // ...
})

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

    jQuery
    JavaScript
    var series = $("#chartContainer").dxChart("getSeriesByPos", 0);
    Angular
    TypeScript
    import { ..., ViewChild } from "@angular/core";
import { DxChartModule, DxChartComponent } from "devextreme-angular";
// ...
export class AppComponent {
    @ViewChild(DxChartComponent, { static: false }) chart: DxChartComponent;
    // Prior to Angular 8
    // @ViewChild(DxChartComponent) chart: DxChartComponent;
    series: any = {};
    getSeries() {
        this.series = this.chart.instance.getSeriesByPos(0);
    }
}
@NgModule({
    imports: [
        // ...
        DxChartModule
    ],
    // ...
})

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.

jQuery
JavaScript
$(function() {
    $("#chartContainer").dxChart({
        // ...
        onSeriesClick: function (e) {
            var series = e.target;
            // ...
        }
    });
});
Angular
HTML
TypeScript
<dx-chart
    (onSeriesClick)="onSeriesClick($event)">
</dx-chart>
import { DxChartModule } from "devextreme-angular";
// ...
export class AppComponent {
    onSeriesClick (e) {
        let series = e.target;
        // ...
    };
}
@NgModule({
    imports: [
        // ...
        DxChartModule
    ],
    // ...
})

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.
