Re: Force graphic to be written to file

Dear NCL users,

I just found that I can output my graphics directly to .epsi format,
setting it in the wks creation.

This saves me one "system(ps2epsi ...)" command every plot, and makes plots
without big white bounds.

Then, you can ignore my last message.

Thank you!

Cheers,
