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.

I don't know. This looks right to me. Here is the code
I used:

cgcontour, cgdemodata(2), xrange=[-12, 11], $
yrange=[-34,33], aspect=67./23

The distance from 0 to 10 on the X axis is the same as
the distance from 0 to 10 on the Y axis. Isn't that
what you wanted, for the distances to be in the same
units?

Cheers,

David
