Hi David,
Thanks for the response!
Does the aspect keyword just keep the aspect ratio of the contour plot the same? I've been running it with multiple contour plots and it looks like the plot width/height is remaining constant while the distances between my tick marks have to adjust to that constant plot and so the distances between my x-ticks and y-ticks are not matching up so my contour does not look right proportionally :(
I'm looking for something where my plot width/height will adjust to keep a constant spacing between tick marks. Like, if there is 1 inch between x=0 and x=10, so then there should also be 1 inch between y=0 and y=10. Depending on what I'm plotting, sometimes my y-axis will go from -10 to 10 and my x-axis will go from -20 to 20, so I want to plot size to be smaller in the y-direction...it should only cover 2 inches whereas my x-axis should cover 4 if we use the example above. Or if my y-axis goes from -15 to 25 and my x from 0 to 10, my y-axis should cover 4 inches and x should cover 1.
Maybe I am doing it incorrectly? Updated code below:
cgContour,z,x,y, /Fill,$
levels=levels, C_colors=Indgen(numLevels(1))+1,$
c_labels=levels, /Outline,$
xminor=5, yminor=5,$
xtickinterval=10, ytickinterval=10,$
xticks=20,yticks=20,$
xstyle=1, ystyle=1,$
Aspect=1.0, /Window
Or would this depend more on the Window than the contour?
Thanks for all the help!

I need to size of the plot itself to be able to change (so if i have 10 major ticks in x and 20 in y, I don't want the plot to be that size when, say, the next plot has 5 ticks in x and 15 in y because then the spacing between the x and y ticks won't be the same). Hope that made sense!
