100% Stacked Area

100% Stacked Area Chart displays multiple series of data as stacked areas, ensuring that the cumulative proportion of each stacked element always totals 100%. The y-axis will hence always be rendered with the range 0–100%. To render a 100% Stacked Area series, use series Type as StackingArea100.
