TdxChartCustomLegend Class
Declaration
TdxChartCustomLegend = class(
TdxChartCustomVisualElement
)Remarks
A diagram can display a legend pane populated with captions of those series in the diagram whose ShowInLegend properties are set to TdxChartSeriesShowInLegend.Diagram. The diagram displays no legend pane if it has no such series or the Legend.Visible property is set to False.
A series is displayed in the Chart control’s legend instead of the corresponding diagram’s legend if the ShowInLegend property of the series is set to TdxChartSeriesShowInLegend.Chart (default).
Simple diagram series display values instead of captions in a diagram or chart legend.
