Re: Position setting of coordinate axis labels
Hi,
Thanks for feedback. Which version of "TeeChart" and "Visual Studio" are you using?
Regards,
Ruben

I am a legitimate registered user of Steema TeeChart for NET Source Code 2017 4.1.2017.02140. I purchased this version for $2400 at that time. I have been asking for a month now. Can the official answer my question

Re: Position setting of coordinate axis labels
Hello,
Apologies for the delay replying. Currently, non-regular angles, (not 0,90,180,270), are not correctly rendering distance from the axis. We are reviewing the code related to this area.

Re: Position setting of coordinate axis labels
Hello,
The issue has been resolved (issues #2651]) and the solution will be included with the next TeeChart update.
I have ported this code back into the relevant method for the sourcecode version, 4.1.2017.02140, and although I am unable to test all possible usage scenarios for this version, it should work for you if you replace this entire method in the Axis.cs unit.:
Alternatively, you can upgrade to the latest version of TeeChart to access the modification directly.

Marc Meumann
