Re: TWorldSeries Pan and Zoom on Mobile

Hello, Panning works fine, and zooming works fine if only one of them is enabled Zoom works alone by drawing a rectangle, isn't it? If you want to zoom by a pinch gesture, you'll need to implement gestures manually like in that application I suggested in the last post. I'll try to do the same with a...

Re: How to edit TChartPreview form?

Hello,

I've seen TTeePreviewPanel was registered only in the Pro version.
I've modified it so it will be registered in TeeChart Standard.
The next maintenance release will include the modification.
Thanks for reporting it and the feedback.

Re: Crash in TFastLineSeries.Clear

Hello, I was going to apply your suggestion and found it was already in our main codebase (so it will be included in the next maintenance release). That could explain why I wasn't able to reproduce the problem. Then I found it was actually a fix proposed by another customer here . I'm sorry for the ...

Re: Crash in TFastLineSeries.Clear

Hello, I see the TFastLineSeries.Clear method was introduced in v2019.28, to fix #2237 . However, since I can't reproduce the problem I can't be sure if that is causing the issue you are observing. Since you own the sources, may I ask you to try and see if removing that method solves the problem for...

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

  • However, there should be lest space between the end of the regular text and the beginning of the sub/superscript
In general we need to calculate the text size with a margin.
This is related to this old issue.

Re: Keeping the Legend Symbols the same size

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...

Re: How to display Greek symbols on axis labels?

Hello,

I'm not sure because I've just seen this is breaking other html tags such as <big> and <small>
So we should revise it.

Re: How to display Greek symbols on axis labels?

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) + '<sub>subscript</sub>' + '<sup>supe...
