100% Stacked Line

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

var chartData = [
    { 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 },
    { x: 'Clothes', y: 70, y1: 30, y2: 60, y3: 180 },
    { x: 'Personal Care', y: 30, y1: 80, y2: 80, y3: 30 },
    { x: 'Books', y: 10, y1: 40, y2: 30, y3: 270 },
    { x: 'Fitness', y: 100, y1: 30, y2: 70, y3: 40 },
    { x: 'Electricity', y: 55, y1: 95, y2: 55, y3: 75 },
