TBeforeRenderTextEvent

Unit: SDL_rchart
Class: none
Declaration: TBeforeRenderTextEvent = procedure (Sender: TObject; var Text: string; Index: integer; IsAnnotation: boolean) of object;

The TBeforeRenderTextEvent is triggered immediately before a text chart item is rendered. The variable parameter Text can be adjusted to the users needs. Depending on the parameter IsAnnotation the parameter Index contains the index into the data or the annotation container. If IsAnnotation is FALSE the text comes from the data container, otherwise the text is from the annotation container.
