Re: Single color panel plots output

If you are getting an error message, please include the full error message in your email.

Are you asking about what to do with this code?

>>> do i=0,2
>>> plot(i) = gsn_csm_contour_map_ce(wks,c,res)
>>> end do

According to your print statements below "c" is two-dimensional, so
it doesn't make sense to loop three times and create the same plot
over and over.

Please give us more information about what you are trying to do.

Thanks,

The only problem i have is to loop files at f1. Can you please look into it and suggest what is wrong. Thanks.
