Name Description

A user cannot select points or series.


A single point or series can be selected at the same time.


Multiple points or series can be selected at the same time.


A user can click a continuous series (lines or areas) to select an entire series:

A line series is selected.

Use the following properties to enable/disable selection for individual series:

You can specify the DxChart.PointSelectionMode (DxPieChart.PointSelectionMode) property to set selection mode for points.


For discrete series (for example, bars), the DxChart.PointSelectionMode property has a higher priority over the DxChart.SeriesSelectionMode property. This means that these properties are not applied simultaneously.


The following example enables selection for a line chart:

  • A user can select multiple points. Points with the same argument are selected when the user selects a point.
  • A user can select an entire series by clicking a line segment. When the user selects a series, the selection of the previously selected series is reset.

Different modes of chart selection are shown
