100% Stacked Area

To render a 100% stacked area series, use series type as StackingArea100 and inject StackingAreaSeries module using Chart.Inject(StackingAreaSeries) method.

import { Chart, StackingAreaSeries, DateTime } from '@syncfusion/ej2-charts';
Chart.Inject(StackingAreaSeries, DateTime);
let chartData: any[] = [
  { x: new Date(2000, 0, 1), y: 0.61, y1: 0.03, y2: 0.48, y3: 0.23 },
  { x: new Date(2001, 0, 1), y: 0.81, y1: 0.05, y2: 0.53, y3: 0.17 },
  { x: new Date(2002, 0, 1), y: 0.91, y1: 0.06, y2: 0.57, y3: 0.17 },
  { x: new Date(2003, 0, 1), y: 1.0, y1: 0.09, y2: 0.61, y3: 0.2 },
  { x: new Date(2004, 0, 1), y: 1.19, y1: 0.14, y2: 0.63, y3: 0.23 },
  { x: new Date(2005, 0, 1), y: 1.47, y1: 0.2, y2: 0.64, y3: 0.36 },
  { x: new Date(2006, 0, 1), y: 1.74, y1: 0.29, y2: 0.66, y3: 0.43 },
  { x: new Date(2007, 0, 1), y: 1.98, y1: 0.46, y2: 0.76, y3: 0.51 },
  { x: new Date(2008, 0, 1), y: 1.99, y1: 0.64, y2: 0.77, y3: 0.72 },
  { x: new Date(2009, 0, 1), y: 1.7, y1: 0.75, y2: 0.55, y3: 1.29 },
  { x: new Date(2010, 0, 1), y: 1.48, y1: 1.06, y2: 0.54, y3: 1.38 },
  { x: new Date(2011, 0, 1), y: 1.38, y1: 1.25, y2: 0.57, y3: 1.82 },
  { x: new Date(2012, 0, 1), y: 1.66, y1: 1.55, y2: 0.61, y3: 2.16 },
  { x: new Date(2013, 0, 1), y: 1.66, y1: 1.55, y2: 0.67, y3: 2.51 },
  { x: new Date(2014, 0, 1), y: 1.67, y1: 1.65, y2: 0.67, y3: 2.61 },
];
let chart: Chart = new Chart(
  {
    primaryXAxis: {
      valueType: 'DateTime',
    },
    series: [
      {
        type: 'StackingArea100', opacity: 0.7, dataSource: chartData,
        fill: 'blue', xName: 'x', yName: 'y',
      },
      {
        type: 'StackingArea100', opacity: 0.7, dataSource: chartData,
        fill: 'black', xName: 'x', yName: 'y1',
