BorderBase Class
Represents the base class for all border objects.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v24.2.dll
Declaration
Remarks
The BorderBase class serves as a base for classes which define the border settings of different chart elements within a chart control.
The settings exposed by the BorderBase class are common to all border types and allow you to specify the border’s color (BorderBase.Color), thickness (BorderBase.Thickness) and visibility (BorderBase.Visible).
Example
This example demonstrates how to access a chart’s Legend and customize its appearance at runtime.
To specify whether series, indicators, Constant Lines, and Strips should be shown in the legend, set their SeriesBase.ShowInLegend, Indicator.ShowInLegend, ConstantLine.ShowInLegend, and Strip.ShowInLegend properties to true.
