Contourplot with white triangles ...
Contourplot with white triangles ...
Hello,
I would like to ask for the status of the known problem with white triangles and difference in isolines and color regions in the contour plot.
I investigated that this issue has been mentioned here a long time ago. But even in the 2010beta (Delphi7) of TeeChart there is still the same problem.
My problem is that I really need this contour plot in my project, but it is not a very professional output with these white triangles.
And this effect is visible in nearly ever real world data set.
So please could the support team supply me the status or even better a solution for this problem?
Bye,
Dirk

Re: Contourplot with white triangles ...
Hello Dirk,
The thread references you posted are up to date. This is a complicated issue to resolve. It's high on our priority list but we haven't a solution to it besides completely redesigning Contour and IsoSurface series. We will keep working on the issue for next releases.

Hi Narcís,
thanks for your rapid reply. So when it is high on the priority list...can I expect a solution in the, let me say, next 2-3 month?
If I can ensure this to my customer it will help me a lot.

Re: Contourplot with white triangles ...
Hi Dirk,
I'm sorry but I can not commit to that for now as the solution seems to be pretty complex and involve changes in many areas.

Re: Contourplot with white triangles ...
Dear Steema Support,
so it is just about one year that we opened this thread (and regarding the first topics that mentioned this issue it is about 3 years..).
I have reviewed each new release and the list of changes. I also verified the most recent release of TChart, but... no solution for this issue.
Sorry but if this issue has been high on your priority list (see above "It's high on our priority list but ...") then I am glad that I have no issue that is low on you priority list
So to be serious again: Could you please tell me about the status and if we finally will have a solution?
Kind regards,
Dirk

Hello Dirk,
Excuse us for the delayed reply.
As Narcís indicated some posts above, I'm afraid this is quite complex and would involve almost the whole redesign of the series type.
Being a high priority item in the list means we consider it is an important feature but the time until it will be fixed also depends on the complexity of the problem and its solution.

Hello,
We haven't closed the bug ticket yet and more changes still need to be studied to get a final solution for the TContourSeries. But we've implemented some modifications to the TIsoSurfaceSeries and it seems to be drawn without the white triangles.
Here it is the code that reproduces the white triangles problem with v2011.03 but seems to work fine with the actual sources:

Series1.IrregularGrid:=true;
Series1.Brush.Style:=bsSolid;
for i:=0 to 9 do
for j:=0 to 24 do
Series1.AddXYZ(i, i*j-random(Round(0.5*i*j)),j);
Chart1.Axes.Left.SetMinMax(0,24);
end;

Re: Contourplot with white triangles ...
Do you have any rough indication of when we can expect this fix to be released?
Re: Contourplot with white triangles ...
Hello,
The modification just announced in my last post will be included in the next maintenance release.
The final fix I'm afraid I can't tell you when.

Re: Contourplot with white triangles ...
Would I be able to get a copy of this modification, please?
I understand that it may not be ready for final release, but I would gladly help test it out if it meant potentially getting it working sooner.

Hello Gerard,
Thanks for the offer.
Since you are an v8 customer and it is a change in the latest sources, we'd need to prepare a new evaluation version for you to do the tests. Could you please tell us what IDE are you using?

Yeray,
No worries; I use C++Builder 2009.

Hi Gerard,
Ok, I have arranged a test installer for you. It's being uploaded now. I'll send you an email with the URL when it's available. Please let us know when you have downloaded it as we will remove it from the website.
Thanks in advance.
