[ncl-talk] gsn_contour_shade

[Laura Fowler]

Hi Adam:
Thanks for your help. Now it did work (see attached plot). Is there a way
by chance to increase the thickness of the individual lines? Looking at the
documentation on gsm_csm_shade, it does not seem to be an option, except
that of increasing the density of lines?

Thanks,
Laura
