Just tested it, and surprisingly it does not work . The exception still happens with this version. (no obfuscation / signing) Since I used a debug build of the teechart source code, I also now tested the local release build, and it also works without the exception. it seems there is still some diffe...

As I stated in my original post, I've already performed that test, and used the equivalent NuGet to the source-code, and got the same exception.
Only when using the code that I've compiled locally, It was working as intended.

Ok, this is getting really weird. I've downloaded the source code for version 4.2022.2.11 compiled it myself with VS2022 (for .NET 4), replaced the assemblies in our project, and tried to reproduce the issue. And to my complete surprise, everything works! I then thought, maybe it is something with t...

Ok, so I'm waiting for the source-code for the chart

But how can we pin-point which font instance (header/footer/etc) is causing the problem? Can I set a default value for all font sizes that isn't zero for all font instances? Was the font-size behavior changed in recent versions of teechart with a default value of zero for fonts compared with previou...

Ok, got some further details:

it appears that the font that has a value of font of the Graphjics3D font is zero.

What affects this value, and how can i change its value?

Ok, now that i understand the problem (font.size=0) somewhere in my code, i need to be able to understand which font.size is causing the issue. I checked for example, the main TChart.FontSize and the Header font. and i saw that while the exception happens they are non-zero values. How can i pinpoint...

Our application is far more complex than a simple view as you have in your examples. And yes, we are suing .NET Framework 4.7 Before trying to reproduce this on a sample application, can you maybe advise me based on the supplied stack-trace and the source code for tee-chart what may cause this type ...

Hi, After upgrading the teechart control to the latest version available (4.2022.4.26) from version (4.1.2014.12153) i'm getting an exception originating from teechart control i didn't had before: System.ArgumentOutOfRangeException HResult=0x80131502 Message=The parameter value must be greater than ...
