ShowGrafNewOnly


Unit: SDL_rchart
Class: TSmithChart
Declaration: procedure ShowGrafNewOnly;

When adding a few drawing elements to an already heavily loaded chart, the update of the graphics takes considerable time. In order to speed up the update in this case the method ShowGrafNewOnly draws only those elements which have been entered into the data container since the last call to ShowGraf

Please note, that ShowGrafNewOnly only redraws the new elements, but not the axes or the grid. Thus ShowGrafNewOnly must not be called if the axes have been changed.
