[ncl-talk] Overlaying two maps with different axes

[Adam Phillips]

Hi Giulio,
It looks like you are attempting to overlay two gsn_csm_xy plots onto one
spatial plot generated by gsn_csm_contour. I believe that is possible, but
your draw/frame calls need to be modified to make this work. Right now you
call draw (=draw the plot)/frame (=flip the page) after creating the
contour plot at lines 263/264. Thus, when you go to overlay the xy plots
the frame has been advanced so there is nothing to overlay on. If you
simply comment 263-264 out I think it will work, as you call draw/frame at
lines 324-325.

If you have any further questions please respond to the ncl-talk email list.
