Edit: The above is precisely the issue. If you uncheck "Allow complex output from real input" then it should work. This issue will be addressed in a future update.

Edit #2: The source is updated to fix two issues recently brought to light: FIX number format, and complex mode. If you redownload the program, it should take care of the issues.

Han, I downloaded and installed the latest version Graph 3D v2.2polytrace (8-JAN-2014)
, but the graph of sqrt(XY) still does not display when complex is checked.
