100% Stacked Line

To render a 100% stacked line series, use series type as StackingLine100 and inject StackingLineSeries module using Chart.Inject(StackingLineSeries) method.

import { Chart, Category, Legend, Tooltip, StackingLineSeries } from '@syncfusion/ej2-charts';
import { Browser } from '@syncfusion/ej2-base';
Chart.Inject(StackingLineSeries, Category, Legend, Tooltip);

/**
 * Sample for StackedLine Series
 */

let chartData: Object[] = [
    { x: 'Food', y: 90, y1: 40, y2: 70, y3: 120 },
    { x: 'Transport', y: 80, y1: 90, y2: 110, y3: 70 },
    { x: 'Medical', y: 50, y1: 80, y2: 120, y3: 50 },
