AutoRedraw


Unit: SDL_rchart
Class: TRChart
Declaration: property AutoRedraw: boolean;

Normally, any action which changes the layout of the chart (for example altering the background color, or changing the displayed range) automatically triggers a redrawing of the chart. While this feature can be quite helpful under most circumstances, there are some applications where the automatic redraw is undesired, since it considerably slows down the drawing process.

For that purpose the automatic redrawing can be switched off by setting the AutoRedraw property to false. In this case the whole chart is only redrawn when the method ShowGraf is called.

Hint: Please note that the AutoRedraw feature has to be switched off in order to be able to draw a mouse trace (by setting MouseAction to maDrawMTrace).
