AutoRedraw


Unit:SDL_polchart
Class:TPolChart
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.
