TdxChartXYSeriesFullStackedAreaView Class
Stores Full-Stacked Area View settings.
Declaration
TdxChartXYSeriesFullStackedAreaView = class(
TdxChartXYSeriesAreaView
)Remarks
An Area View displays series values as filled areas on a diagram. The peaks and hollows in the filled areas reflect series point values. All Area Views support the same line appearance settings for filled area borders as Line Views.
The TdxChartXYSeriesFullStackedAreaView class implements the Full-Stacked Area View designed to display series as stacked areas on a diagram. Unlike the Stacked Area View, stacked areas always occupy an entire diagram area by height, and the axis of values displays percentage values. Use this View when you display multiple series and you need to emphasize percentage contribution of each series. To select the Full-Stacked Area View, assign 'FullStackedArea' to the ViewType property of an XY series.
