IUiChartGetDataValueEventArgs.Editable

Syntax

Editable: Boolean;

Description

The Editable property determines whether a series value can be edited in this point. If this property is set to False, the UiChart.OnSetDataValue event is not called for this series point.

Example

Sub UiChartOnGetDataValue(Sender: Object; Args: IUiChartGetDataValueEventArgs);

Begin

Args.Result := True;

Args.Value := Args.PointIndex + Args.SerieIndex;

If (Args.SerieIndex = 0) Then

Args.Editable := False;

End If;

End Sub UiChartOnGetDataValue;

Executing the example plots a chart, comprising direct lines, which number and length depend on the specified number of graph series and points. Editing will be disabled for the first series points.
