There were some changes (in one of the previous versions) regarding the saving / loading, but old design files should be compatible with newer versions. What was your previous version (before the upgrade)?
You are very quick to test new functionalities... 🙂
I have implemented auto-scaling in horizontal and vertical direction independently. Please replace "ASC" with "YASC". If you need to control scaling in horizontal direction, please use "XASC" (available for XY chart only).
I promise that the XASC and YASC parameters will not change in the future.
