Is There a Python Window Command?

[toml_12953]

I can use Python graphics on Prime with no problem but they're pixel-oriented and I have to manipulate the graphics to fit the screen. Is there a way to redefine the screen limits the way you can do in HPPL? I tried setting Xmin, Xmax, Ymin and Ymax but no change. I also tried eval() with those variables. Are there other graphics commands for line() and pixon() that respect the set screen coordinates? I was sure I had some Prime Python documentation but, of course, I can't find it now.
