It does not work for the method of using gsn_csm_xy (for bar) and gsn_add_annotation (for curves), which is the way to go if multiple curves are overlaid to a bar plot. Plus, modifying vp setting in that case will change the fontheight of labels/axis.

You're right, if you are attaching additional stuff to the outside of a plot using gsn_add_annotation, then the method I mentioned won't work.

But, I think you should be able to still set the vp resources as I described, and then instead of using gsnMaximize, you can use maximize_output.

See these example for more information:

http://www.ncl.ucar.edu/Applications/xy.shtml#ex26 (xy_26.ncl and xy_27.ncl)

Note that in this case, you do *not* want to set gsnMaximize to True.
