TdxChartXYSeriesBarView Class

Stores Bar View settings.

Declaration

TdxChartXYSeriesBarView = class(
    TdxChartXYSeriesCustomBarView
)

Remarks

A Bar View displays series as sets of vertical or horizontal bars depending on axis positions. Bar lengths reflect series point values. Bar Views are often used to compare values in different categories.

The TdxChartXYSeriesBarView class implements the Simple Bar View that displays series values as colored bars grouped by argument values (categories). Use this View when you need to display only one series or when you need to compare multiple series.
