TdxChartGetValueLabelDrawParametersEvent = procedure(Sender: TdxChartCustomDiagram; AArgs: TdxChartGetValueLabelDrawParametersEventArgs) of object;

Name	Type	Description
Sender	TdxChartCustomDiagram	The diagram that raised the label parameter customization event. Cast this parameter value to the TdxChartXYDiagram or TdxChartSimpleDiagram class depending on the actual diagram type to access all public API members. You can call the `Sender`.ClassName function to identify the diagram type.
AArgs	TdxChartGetValueLabelDrawParametersEventArgs	Provides access to draw parameters of the processed series value label in the diagram accessible through the `Sender` parameter. You can use the `AArgs`.Text property to change display text of the processed series value label.

You can use the AArgs.SeriesPoint property to identify the processed value label. Refer to the TdxChartGetValueLabelDrawParametersEventArgs class description for detailed information on available options.

The OnGetValueLabelDrawParameters event of XY and simple diagrams references the TdxChartGetValueLabelDrawParametersEvent procedural type.
