Sub OnGetPointName(Sender: Object; Args: IUiChartPointNameEventArgs);
Begin
//set of operators
End Sub OnGetPointName;
The Sender parameter returns the component that has generated the event.
The Args parameter allows to define event parameters.
The OnGetPointName event enables to determine names of points on the graph. This event occurs when a chart is drawn.
This example assumes that there is the Chart object of the IChart type.
Sub UiChartOnGetPointName(Sender: Object; Args: IUiChartPointNameEventArgs);
Begin
Args.Result := "point " + Args.PointIndex.ToString As String;
End Sub UiChartOnGetPointName;
After executing the example names of graph points are changed: Point 0, point 1 and so on.
