Public Property LastPoint As SidePoint
| Type | Description |
|---|---|
| SidePoint |
A SidePoint object that contains settings for the last series point.
|
LastPoint specifies how the chart displays the last point and its related visual elements.
The LastPoint.LabelDisplayMode property defines how to display the point’s label.
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.
|
| |
SeriesPoint
|
The control shows the label next to the series point. If the label should be outside a visual area when zooming or scrolling, the label is displayed at the diagram’s edge. The SidePoint.Label property specifies appearance settings.
|
|
Use the LastPoint.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.
You can specify how to display markers in series that support markers (for example, Line or Point). To do this, use the RangeAreaSeries2D.MarkerDisplayMode or SegmentSeries2DBase.MarkerDisplayMode property according to your series type. To show the marker on the last series point, set MarkerDisplayMode to SidePointDisplayMode.SeriesPoint. To display it on the diagram’s edge, set MarkerDisplayMode to SidePointDisplayMode.DiagramEdge.
This example demonstrates how to create a template that customizes the last label appearance.
To show its label, set the LastPoint.LabelDisplayMode property to SeriesPoint.
The markup below specifies SeriesLabel.ElementTemplate and customizes the label appearance:
Set MarkerDisplayMode to SeriesPoint to display the last point marker.
Set LineSeries2D.MarkerVisible to False to hide other markers.
