incorrect holes in surface series

[Track1]

Does anybody know the setting to resolve these incorrectly filled surfaces on a contour and IsoSurface series?

This seemed to have occurred since upgrading to TeeChart Pro 2012.05.120327, but i cannot seem to resolve.
The holes are not in my data. There must be some setting but I cannot find it.

Thanks

Hi,

This seems to be the same discussed here.
I'm afraid [TV52012990] hasn't been fixed yet.

[Track1]

Wow!!!
This defect was identified four (4) years ago - and 4 years later it's still waiting to be fixed?
It must be either very hard to resolve or lost... Can we revive it please Steema?
Many thanks

Hi,

It's also identified in [TV52013073]. Here you have some of the topics where it was discussed:

Thank you Yeeray
I had looked at all of those, and more, trying to find a way to resolve.
I definitely have the values as specified, but it did not cure the problem with the display

IsoTTChartSeries.UseColorRange := False;
IsoTTChartSeries.UsePalette := True;

Those other posts are also more than 2 years old, that's why I was sure this known issue would be resolved by now... I was wrong

Appreciate if Steema could advance this

Hi,

It would be helpful if we could identify what maintenance release broke this. You said:

This seemed to have occurred since upgrading to TeeChart Pro 2012.05.120327, but i cannot seem to resolve.

In the threads mentioned above, the problem seems to be reproducible since TeeChart v8. But I see you had TeeChart v7, v8 and v2010 before the actual. So, could you please tell us what was the latest exact maintenance release it seemed to work fine for you?

[Track1]

Thanks Yeeray

I'm not absolutely positive that it broke from a maintenance release. I had seen this before but not for some time, so I thought a setting I had chosen must have resolved it. I may be wrong on that point though

However, before this version I can advise that I was definitely running TeeChart Pro 8.06.60902

On the computer with the issues, I am now definitely running

Hi,

Revising the threads where this was discussed, I see a customer who found it solved with an installer we made for him.
Could you please tell us what IDE are you using so we can try the same?
It would also be helpful if you could send us a simple example project we can run as-is to reproduce the problem here so we can check it here too.

Thank you Yeeray

In this application I am using Delphi 6 and Steema Tee Chart Pro 2012.05.120327

I also run RAD Studio XE and XE2 but cannot upgrade this project to that platform due to other limitations

Please find attached sample project and data set that replicates the problem in both Iso and Contour formats

The exe has been removed because of size limitations with the upload. If you need the complete set with the exe it is currently available from this link: http://www.advantechdesign.com.au/IsoChartHolesTest.zip

Hi Trevor,

I'm afraid the same build that solved the problem for that customer, doesn't seem to solve the problem in your example.
The TSurfaceSeries seems to be drawn without this problem, but the TContourSeries.

Code: Select all

var tmp: TChartSeries;
//...
  tmp:=MyContourSeries;
  ChangeSeriesType(tmp, TSurfaceSeries);

We're still investigating this and we'll be back to you as soon as we get some conclusion.

Hi Trevor,

Excuse us for the delayed reply here.
I found the v2011.03 seems to work fine for me here with your application. Could you please give it a try?

[Track1]

Thanks

Where do I download from? Can you supply a link?

Is this a retrograde (downgrade) from the existing version I have

thanks

Hi Yeeray
I downloaded but haven't' installed yet. Where can I find the differences between the versions?

Can Steema put the changes that are in 2011.03 that resolve the issue into the latest version? It would seem that it is more appropriate to move forward rather than downgrade to resolve.

Many thanks for your support

Hi Trevor,

The changes introduced that broke this for your dataset were applied to fix a similar problem with another particular dataset. Reverting the changes would fix the problem in your case but make it reappear some other customer(s). I thought the best solution is to study this particular case and try to find a fix for it. That's why I suggested you an old maintenance release in the meanwhile.

Since you are a source code customer, you could also try to copy the v2011.03 TeeSurfa.pas file in the v2012.05 sources, backing up & overwriting the v2012.05 TeeSurfa.pas and try to recompile the v2012.05 sources. This works for me in D7 but I haven't tried it for XE/XE2.

Hello Yeeray

I downloaded and installed 2011.03 Delphi6 (binary installer version)

TeeChartPro2011.03.png (104.92 KiB) Viewed 12794 times

Unfortunately, the problem was not resolved with that version.

I could never get the 2012 source code installer to work, see: http://www.teechart.net/support/viewtop ... =3&t=13167, so I only had the 2012 binary installer working.

I downloaded and installed the source code version for 2011.03, and the result was exactly the same as above

How can I provide further assistance to Steema to resolve?

Many thanks

Trevor
