Stacked Area

To render a stacked area series, use series type as StackingArea and inject StackingAreaSeries module using Chart.Inject(StackingAreaSeries) method.

import { Chart, StackingAreaSeries, DateTime } from '@syncfusion/ej2-charts';
import { stackedData } from './datasource.ts';
Chart.Inject(StackingStepAreaSeries, DateTime);

let chart: Chart = new Chart({
        series: [
            {
                dataSource: stackedData, xName: 'x', yName: 'y',
                //Series type as stacked area series
                type: 'StackingStepArea',
            },
            {
                dataSource: stackedData, xName: 'x', yName: 'y2',
                type: 'StackingStepArea',
            }
        ],

}, '#element');

Series customization

The following properties can be used to customize the stacked step area series.

  • fill – Specifies the color of the area series.
  • opacity – Specifies the opacity of fill.
  • dashArray – Specifies the dashes of series.
import { Chart, StackingAreaSeries, DateTime } from '@syncfusion/ej2-charts';
import { stackedData } from './datasource.ts';
Chart.Inject(StackingStepAreaSeries, DateTime);

let chart: Chart = new Chart({
        series: [
            {
                dataSource: stackedData, xName: 'x', yName: 'y',
                //Series type as stacked area series
                type: 'StackingStepArea', fill: 'red',
                border: {width: 2, color: 'yellow'}, dashArray: '5.5'
            }, {
                dataSource: stackedData, xName: 'x', yName: 'y2',
                type: 'StackingStepArea', fill: 'green', border: {width: 2, color: 'yellow'}, dashArray: '5.5'
            }
        ],

}, '#element');
