Calling ds.Reset make the fix. I also think that Reset could be called by EndUpdate.

If I comment the line " if not RectIntersectsRect(ext, ParentChart.CurrentExtent) then exit;" in the TASeries.pas unit then the series is drawing properly. Ah, I see now. You need to call ds.Reset before ds.EndUpdate. Maybe Reset should be called automatically by EndUpdate... -- Alexander S.
