[gradsusr] How to plot power spectrum

Wed May 1 08:38:08 EDT 2013

Dear Grads users,

Is it possible to plot a power spectrum in Grads? If yes then how is it done? I am working on OLR data from 1998-2011 for JJAS months. I need to plot power spectra at place of maximum variance. I already have calculated variance for above months. Please help.

Thank you!

Yours sincerely,
