Hello,

Drawing a million lines is always slow. That's why the majority of techniques we use to improve drawing performance involve reducing the number of lines to be drawn as you can see here.

Hello,

I've been able to reproduce the problem so I've added it to the public tracker (#2528).
Thanks for reporting it.

Hello,

Can you please send me a simple executable to run here?

Sure, find it here. I've tested it in a Win11 VM and it seems to work fine.

Hello,

Sorry for the delayed reply here.
The problem seems to be on the shadow drawing.
Could you please confirm if hiding it solves the problem for you?

Hello,

Sorry for the late reply here.
I've done a simple example project to test this and it seems to work without errors for me in RAD 11.1, both with the new and the classic compiler. Please, give it a try at the project above and let us know if it works fine for you.

Hello Rick, Excuse us for the delay here. We've done various changes fixing some of the memory leaks you reported, and adding responsiveness to the TChartListBox . I'll send you the changes so you can take a look at them. We still find a memory leak but it looks smaller than before. I'm also sending...

Hello Jürgen, Are those .bpl files in the specified folder? If they aren't, the installation may have failed for some reason. Try a full TeeChart reinstall with high privileges. To do so, you can run the installer "as administrator". If those .bpls are present and the IDE is failing to find them, pl...

Hello,

Thanks for the description but I'm not sure how are you exactly generating that pdf.
Can you please arrange a simple example project we can run as-is to reproduce the problem here?
Thanks in advance.

Hello, Thanks for the detailed report. I get slightly different issues here (*) so I'm investigating if there's something I'm missing. (*) I get an access violation when I connect the TChartListBox to the TChart at design-time and try to run the project. Then, when the IDE returns to the design view...

Hello, I'm afraid there was some mistake there. I've checked the source code includes the patches mentioned in the release notes. So the mistake should only affect TeeConst.pas. These are the correct values for TeeConst.pas: TeeVCLMinorVersion ='.35'; // ie: '.01' '.02' , etc TeeVCLBuildVersion ='22...

Hello, Indeed, I couldn't reproduce any error with that project. Could you please try creating it by code? var ChartTool1: TLegendPaletteTool; procedure TForm1.FormCreate(Sender: TObject); begin ChartTool1:=TLegendPaletteTool.Create(Chart1); Chart1.Tools.Add(ChartTool1); ChartTool1.Series:=Series1; ...

Did your search for the error message text include the TQRChart sources?

Yes, I did without any match.

Hello,

I've tried with the example here and got a 'EDatabaseError' exception with the message:

Dbf1 : Operation not allowed, dataset "Dbf1" is not in an edit or insert state.

Not exactly the same error you reported, but enough to add it to bugzilla (#2524).
