The SidePoint class members specify how the chart displays the first and last points and their visual elements.
The SidePoint.LabelDisplayMode property defines how to display side point labels.
The following values are available:
Value | Description | |
|---|---|---|
Default | The label uses common label settings. |
|
DiagramEdge | The control displays the label at the diagram edge. The SidePoint.Label property specifies appearance settings. |

Use the SidePoint.Label property to customize label’s text color, border options, text pattern, and other settings. Refer to the SeriesLabel’s Properties page for a list of available options.
Example
This example shows how to create a template that customizes the side point label appearance.
Use the XYSeries2D.FirstPoint and LastPoint properties to access side point options.
To show labels, set the SidePoint.LabelDisplayMode property to SeriesPoint.
The markup below specifies SeriesLabel.ElementTemplate and customizes the first label appearance:
- background color
- text color
- font size
- border corner radius
- border thickness
The last point label uses default settings.
