Hi,

I use D2007 and TChart V8.02. The TSurfaceseries are not plot all datapoints, with D6 and TChart V7.12 it is ok. I have IrregularGrid set to true. This is very annoying, because I have verified with the V7.12 and there it was ok, but with the new Version 8.01 and 8.02 it was not ok.
I can send you the screenshots and the program if it is useful.

Where I can it upload to ?

Second problem : with V8.02 I can't compile it with TeeSingleValue !

best regards
Werner

In addition, depending on the data an exception occurs, with V7.12 is all ok.

Hi Werner,

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.

Thanks in advance.

Hi Narcis,
thank you for your reply, I have upload SurfaceBug.zip including
the sources for D6 and D2007, the exe file for D2007, a documentation how to get the problem and a data file. I hope you can find the problem very soon.

Hi Werner,

Thanks for the example project.

I'm not able to reproduce the issue here with v8.02 and Delphi 2007 because when I try loading the data file, as shown in the document you sent, I get this error message:

Project Test3d.exe raised exception class EConvertError with message ''' is not a valid integer value'.

Program doesn't crash when setting threshold to 10.

I can't even compile the Delphi 6 version as it uses several third party components we don't have: TB97Ctls, TB97, TB97Tlbr, ToolEdit and CurrEdit.

Could you please modify your project or let us know how can we run it here successfully?

Thanks in advance.

Dear Narcis,
for D2007 two ways you can go :
1: compile the program with tools/options/debugoptions/codegear-debugger/language-exceptions

Checkbox 'message at language exceptions' unchecked to run thru
the try-except-end section.

2. or leave Treshold not als blank.
For the first step enter -10 into the treshold and load then the file.

The next step is to enter 10 into treshold and load the file again, now you should see the problem.

I have uploaded the modified sources (SurfaceBugsource.zip), so you can compile it with D6 witout 3rd party components.

With best regards
Werner

Dear Narcis,

are you able to reproduce the problem?

Is there a solution for the problem ?

Hi Werner,

We have been doing some tests and we could reproduce the problem here but can't get it working using TeeChart Pro v7.12 VCL source code available at the client download area.

Could you please confirm the exact TeeChart version you used to get the application working so that we can check the differences between versions?

Thanks in advance.

Hi Narcis,

the About says Teechart Pro V7.12, but the relase note says V7.07.
I have it checked, both are working (V7.12 and V7.07).

Hi Werner,

Thanks for the information.

We haven't been able to get your example working in v7 either. We made tests in several v7 installations in different machines. We have added this issue (TV52012645) to our defect list to be fixed for future releases.

Can you get this working in v7 in a different machine? It would be very helpful finding a consistent way to have this working in v7 as then it would be much easier finding the cause of the problem.

In the meantime, if it works fine with v7 at your end, I can't think of any other solution than using v7.

Thanks in advance.

Hi Narcis,

thank you for your reply.
I have it checked on another machine with V7.07 and delphi 6. On this machine it works as well as with the other machine with V7.12.
What was the problem you have with V7.07 or V7.12 ?

The major reason I changed to V8.2 is the TCountourseries, which I need functional and with the features of V8.02.

Is there a way to use V7.12 with the features for TContourseries of V8.02 ?

If not , I have to use V8.02 and I don't like to run into a problem with the TSurfaceseries. The project I develope goes live in the first quarter of next year.

Hi Werner,

Thanks for the information.

The same as with v8.02.

Is there a way to use V7.12 with the features for TContourseries of V8.02 ?

This may only be possible if you are a sourcecode customer and wouldn't be easy as those features should be ported from v8 to v7 and most likely wouldn't just involve changes in TContourSeries.

Hi Werner,

I have revisited TV52012645 now and it works fine for me here with Delphi 2007 and current v8 sources. I'll send you an e-mail with the URL to download them. Could you please check if they solve the problem at your end?

Thanks in advance.

Hi Narcis,

sorry for the delay.

I have checked the new sources and it seems to work for this issue.

with best regards

Werner

Hi Werner,

No problem, thanks for confirming!
