Re: Crash in TFastLineSeries.Clear

Hello, I've been trying to reproduce the problem with your code in a simple example without success. The call stack looks like the one you've posted but Clear method ends without errors.

Ie: var i: Integer; begin for i:=0 to Series1.Count-1 do with TPointSeries(Chart1.AddSeries(TPointSeries)) do begin Pointer.Pen.Visible:=False; Pointer.Size:=6; Ti...

Re: How to display Greek symbols on axis labels?

Hello,

So we should revise it.

Anyway, the base of the code would be this: procedure TForm1.Chart1AfterDraw(Sender: TObject); {$IFNDEF CLX} var UnicodeString : WideString; {$ENDIF} begin inherited; {$IFNDEF CLX} SetLength(UnicodeString, 1); Un...

Re: PieChart with words of different size

Hello,
