property AutoRepaint: Boolean;

Unit
Series

Description

The AutoRepaint property controls if the Fast-Line series displays completely all its points when a new point is added to the series or a point X Y values are modified.

Setting AutoRepaint to False makes the fast-line series to draw new added points only, without repainting the whole chart and series.

Note: The Fast-Line series AutoRepaint property is not the same as the Chart AutoRepaint property.

Note: Axes scales should be big enough to accomodate new point values when AutoRepaint is False.

Example:

var t : Integer;

Chart1.BottomAxis.SetMinMax( 0, 1000 );

Series1.AutoRepaint := False;
for t:=1 to 1000 do Series1.Add( Random( 1000 ) );
Series1.AutoRepaint := True;
