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(StackingAreaSeries, DateTime);

let chart: Chart = new Chart({
        series: [
            {
                dataSource: stackedData, xName: 'x', yName: 'y',
                //Series type as stacked area series
                type: 'StackingArea',
            }, {
                dataSource: stackedData, xName: 'x', yName: 'y1',
                type: 'StackingArea',
            }, {
                dataSource: stackedData, xName: 'x', yName: 'y2',
                type: 'StackingArea',
            }
        ],

}, '#element');

    },
    series: [
        {
            type: 'StackingArea', opacity: 0.7,
            dataSource: [
                    { x: new Date(2000, 0, 1), y: 0.03 },
                    { x: new Date(2001, 0, 1), y: 0.05 }, { x: new Date(2002, 0, 1), y: 0.06 },

                    { x: new Date(2009, 0, 1), y: 0.75 }, { x: new Date(2010, 0, 1), y: 1.06 },
                    { x: new Date(2011, 0, 1), y: 1.25 }, { x: new Date(2012, 0, 1), y: 1.55 },
