Example

This example shows how to customize side series points.

Use the XYDiagramSeriesViewBase.FirstPoint and LastPoint properties to access side point options.

To show labels, set the SidePoint.LabelDisplayMode property to SeriesPoint.

The code below customizes the following options of the first label:

• background color
• line color
• border color
• border thickness
• text color
• text pattern

The last point label uses default settings.

C#

LineSeriesView seriesView = (LineSeriesView)chartControl1.Series[0].View;

seriesView.FirstPoint.LabelDisplayMode = SidePointDisplayMode.SeriesPoint;
seriesView.LastPoint.LabelDisplayMode = SidePointDisplayMode.SeriesPoint;

seriesView.FirstPoint.Label.BackColor = Color.LightGray;
seriesView.FirstPoint.Label.LineColor = Color.Red;

seriesView.FirstPoint.Label.Border.Color = Color.Red;
seriesView.FirstPoint.Label.Border.Thickness = 2;

seriesView.FirstPoint.Label.TextColor = Color.Red;
seriesView.FirstPoint.Label.TextPattern = "{V:F2}";

VB.NET

Dim seriesView As LineSeriesView = CType(chartControl1.Series(0).View, LineSeriesView)

seriesView.FirstPoint.LabelDisplayMode = SidePointDisplayMode.SeriesPoint
seriesView.LastPoint.LabelDisplayMode = SidePointDisplayMode.SeriesPoint

seriesView.FirstPoint.Label.BackColor = Color.LightGray
seriesView.FirstPoint.Label.LineColor = Color.Red

seriesView.FirstPoint.Label.Border.Color = Color.Red
seriesView.FirstPoint.Label.Border.Thickness = 2
