Unit: SDL_scale
Class: none
Declaration: TScaleTickDrawnEvent = procedure (Sender: TObject; Canvas: TCanvas; ScaleType: TScaleType; CurrentTickPos: double; ChartX, ChartY: integer) of object;

The TScaleTickDrawnEvent declares the OnScaleTickDrawn event (components RChart, PolChart, and Scale) which may be used to draw user defined parts in the chart.
