Hello,
today I installed your new TeeChart V8.02 with no problems. Then i tried to compile a project with TSurfaceSeries. There are the same problems Werner had with his TSurfaceSeries in December 2007. I have set Series2 IrregularGrid to true. With TeeChart 7.07 and delphi 7 there was no problem to display the chart.
But otherwise than Werner i can't use TeeChart 7.07 no more.
There must a solution in TeeChart 8.
Can you help me?

If you want i can send you pictures of both TSurfaceSeries.

Your sincerely
Willi

Hi Willi,

As I said in Werner's thread, this is a bug (TV52012645) and there's little that can be done until the bug is fixed.

Also, as you can read in that thread, we couldn't get Werner's application work fine in v7 either.

Hello,
but if the bug is not fixed I can't use TeeChart v8. And if I knew that this bug exist I didn’t bought TeeChart V8. TSurfaceSeries is very important to us. Can I do anything that you can fix this bug? Or if you don’t fix this we have to give back TeeChart V8.

Your sincerely

Hi Willi,

This is a high priority item in v8's bug list. However I can't give you an estimate date of when it will be fixed. I strongly recommend you to be aware at this forum or subscribe to our RSS feed for new release announcements and what's being fixed on them.

Hi Willi,

As I posted here it seems TV52012645 has been solved. I'll send you the sources I sent to Werner so that you can check them at your end.

Thanks in advance.

Hello,
it seams that this bug is fixed with your new source. But there are still problems with TSurfaceSeries and OpenGl, the TVideotool still produce a access violation if the TeeOpenGl is active and TIsoSurfaceSeries paints still wrong it TeeOpenGl is active, too. In both cases there are now errors it TeeOpenGl is not active.

Hi Willi,

it seams that this bug is fixed with your new source.

Thank you very much for testing!

But there are still problems with TSurfaceSeries and OpenGl

Which are the exact problems here?

the TVideotool still produce a access violation if the TeeOpenGl is active

We did some tests here and we think it's not a TVideoTool problem but an OpenGL problem. Code below fails when last line is commented out. Can you please confirm this one?

Code: Select all

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1.AddSeries(TTriSurfaceSeries.Create(nil));
  Chart1[0].FillSampleValues();

  TeeOpenGL1 := TTeeOpenGL.Create(nil);
  TeeOpenGL1.TeePanel := Chart1;
  TeeOpenGL1.Active := true;

//  (Chart1[0] as TTriSurfaceSeries).Transparency := 1;
end;

TIsoSurfaceSeries paints still wrong it TeeOpenGl is active, too.

I'm not able to reproduce this one. Could you please send us a simple example project we can run "as-is" to reproduce the problem here? You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

In both cases there are now errors it TeeOpenGl is not active.

I'm not sure about what you mean here. Could you please give us some more details about this one?

Thanks in advance.

Hello,
i don't use TTriSurfaceSeries and so I don't have the line (Chart1[0] as TTriSurfaceSeries).Transparency := 1; in my code. Sorry. For the difference between TSurfaceSeries and TIsoSurfaceSeries with OpenGl active I have uploaded two pictures for a TChart from the same data.

Your sincerely

Hi Willi,

Excuse us. Yes, this is still reproducible.

And about this, I still couldn't reproduce it:
