Hi,

We found a possible defect in TeeChart library.

Chart series marks which are beyond chart area do not disappear (while chart point markers are hidden).

This happens after chart is scrolled/zoomed, so that some of points get out of chart area. Point markers for them are hidden, while series marks are still visible.

Issue was confirmed on demo application provided with TeeChart.

See attached screenshots.

Hi Sebastian,

You can use Marks.Clip as suggested here or you can use OnGetMarkText:

Code: Select all

procedure TForm1.Series1GetMarkText(Sender: TChartSeries; ValueIndex: Integer; var MarkText: String);
begin
  if not PointInRect(Chart1.ChartRect, Sender.CalcXPos(ValueIndex), Sender.CalcYPos(ValueIndex)) then
    MarkText:='';
end;
