Yep, it's exactly what I wanted.
And your code works for me, too.
I stripped my cgContour command down to the bare minimum and it worked(just the data, ranges, and aspect). Then started adding the extra stuff, and it worked fine until the /Window keyboard. Seems that's what is making my plot go crazy. Any reason why this should be? I added it to the code you posted, also, and /Window causes issues with that too.

For example, I just plotted something with x=[-12,11] y=[-34,33], asp=2.91304 (i put a stop in my code and checked to see that all these values are correct and they are). But when it actually plots, the y-axis looks almost 5 times bigger than the x...which is not what I told it to do.
