hi, Mark
Thx for your suggestions.
A simple axis conversion might not work. For example, if I use x_new = x_old/10, y_new = y_old/20. If shifts my x/y differently, and the shape of my wafer map is not a circle anymore.
I figure out a walk-around by myself. In the defined x/y column, I edit column property: axis to not show default ticks. Instead, I re-define my coordinates as reference lines(not show the line though). This works for me since I don't have too many ordinates to define. If it is more complicated coordinate system, we need extra script to handle this part.
