Example
With DXCharts, you can fully customize the appearance and behavior of chart titles. For example, this sample illustrates how to display a group of check boxes, which control series visibility, in a chart title’s area.
To accomplish this task, it is necessary to define a WrapPanel with a set of CheckBox elements, and bind their check state to a Series.Visible
property of the corresponding series. Then this WrapPanel can be placed as a chart title into a ChartControlBase.Titles collection.
