SuppressPaint

Declaration: ChartBook.Charts[].SuppressPaint: boolean;
Some of the properties and methods of the charts will trigger a repaint process (which is comparatively slow). This may result in unnecessary repaint operations (flicker!) if several parameters of the chart are to be changed at once. It is therefore recommended to temporarily switch off repainting by setting SuppressPaint to TRUE when several parameters are to be changed programmatically.

Do not forget to set SuppressPaint to FALSE again after all changes are completed, otherwise the chart will be blocked.

Hint: The method Update has the same effect as setting SuppressPaint from TRUE to FALSE.
