First of all, I need to confirm that the defect TV52012275 still exists in the version 8.02. This is connected with MinimumRound and MaximumRound properties and the way how Axis rectange is calculated (see CalcRoundScales function). You may be interested to read my posts in the private beta test gro...

Dear Mr. Marc Meumann, Please note, that my initial post was related to the latest TeeChart 8.01 (September) release. I had submitted a test case project clearly demonstrating a problem(s) in the Chart Editor, when it works in tree mode. Unortunately I didn't receive a constructive reply on the subj...

I just uploaded to Steema upload page an example revealing a bug in Logarithmic axis mode (file LogAxisBug.zip). The project includes a precompiled executable. The bug is clearly seen in debug mode when the project was compiled with range check = on. The exception raises in the "TeEngine.pas" (versi...

Hi Narcis, Thank you for the update! I recompiled TeeChart 8.01 and after this step recompiled my applications (they all use TeeChart run-time packages). Preliminary testing in Windows 98 Second Edition English (Virtual Machine) shows that compatibility now restored. At least all my applications now...

Hi Narcis, These changes unfortunately don't help. The reason is simple. You eliminated the calls to these 2 functions at Win98 platforms, but the functions are still present in the import table! Thus any application using this unit or the package TeePro811.bpl will fail at Win98, Me. You need to im...

I can not find explicit declaration concerning supported target platforms for the latest version. Do you include Windows 98, Me? Unit TeeNumericGauge.pas (package TeePro811.bpl) uses calls to AddFontMemResourceEx and RemoveFontMemResourceEx . According to MSDN documentation: Requirements Windows NT/...

Hi Narcis,

Yes, I am source code customer, of course (see my other reports). But in any case I am trying to avoid TeeChart code modifications, introducing customization in derived classes.

Best regards,

It would be nice to have an ability to modify the value of TeeMsg_EditorKey (TeeConst.pas file) in future versions of TeeChart. Such modifications will allow to save ChartEditor settings on per-application basis adding more flexibility. Currently it is declared as const :cry: thus location is fixed:...

Hi Narcis, Of course, I know that the problem is caused by timer. I used timer in order to simulate much more complicated situation typical for multithreaded applications: some thread computes something and updates the contents of a chart from time to time (of course, in the contest of the main thre...

Hi Narcis, I believe that this example helps to reveal several similar problems. You will be able to obtain errors in different places of Teechart using different sequencies of node selections. For example, try to select "Data" node first, or try to play with Series node and its subnode. Best regard...

Hi Narcis, As you suggested I decided to start a new thread concerning Chart Editor (Tree mode) problems. Probably there are several issues, but lets consider them one by one. I uploaded "Miket_ChartEditor.zip" (steema upload page) with a project (Rad studio 2007 Win32) demonstrating the probrem(s)....

Hi Narcis, I just uploaded "Miket_ChartEditor.zip" with a project (Rad studio 2007 Win32) demonstrating the probrem(s). Please, see comments in the source file for details. I am ready to test all modifications of the source. In my big project I often face the situation when something is modifying a ...

Hi Narcis, By some reason the fix for the defect { 8.0 - TV52012099 } was not included to 8.01 version (September release). I reported this issue in steema.private.fieldtest.teechart8 on Feb 23 2007 and you suggested the fix in the post Feb 27 2007. Why this fix disappeared from 8.01 release? Are th...

Hi Narcis,

Thank you for the information! Unfortunately there are still some issues in Chart Editor (Tree mode). I posted another message related to these issues.

Hi Josep,

Thank you for the fix, now everything works fine!

Best regards,
Michael
