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. While you can't send us a simple example, if you can tell us in what TeeChart version you weren't reproducing the...

Hello, An alternative would be to hide the pie series from the legend and use a point series for each item you want to be in the legend. 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...

Hello,

This is an issue already in the public tracker (#1907) I'm currently revising.

Hello,

You missed this part in your code:

Hello, You could use ttfHtml font format as follows: procedure TForm1.FormCreate(Sender: TObject); begin Chart1.Title.Font.Size:=18; Chart1.Title.Font.Name:='Arial Unicode MS'; Chart1.Title.TextFormat:=ttfHtml; Chart1.Title.Text.Text:='Theta: ' + WideChar($0398) + '_subscript' + '<sup>supe...

Hello, I'm not sure if you want to draw it in the axis title or in all the axis labels. 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...

Hello,

Try to open TeePreviewPanel unit first.

Hello, Is this what you are trying to achieve? Project1_2020-03-06_11-57-48.png This is the code I used to draw the above: constructor TForm1.Create(aOwner: TComponent); var lValue: currency; I: Integer; lCaption: string; begin inherited; for I := 1 to 5 do begin lValue := Trunc(Random(1000)); lCapt...

Hello,

If you still find problems with it, please try to arrange a simple example project we can run as-is to reproduce the problem here.

Hello,

Even if you can calculate the size of each word, the dificult part, as far as I see, would be to calculate the position of each word so a group of words draw something similar to a given shape, the pie slice.

Hello, I'm using an array to store the values to be displayed on the top but using a datasource should also work: var topValues: array of double = [1250.30, 1360.60, 1610.14]; procedure TForm1.PopulateSeries(ACount: Integer); var i: Integer; begin FormatSettings.DecimalSeparator:=','; FormatSettings...

Hello, We'd need a simple example project we can run as-is to reproduce the problem here because I see no problems trying to achieve what I'm understanding you described: Project1_2020-03-05_09-40-41.png Project1_2020-03-05_09-40-45.png uses Series; procedure TForm1.PopulateSeries(ACount: Integer); ...
