[ncl-talk] Error: gsn plot: All of the plots passed to gsn_panel appear to be invalid

[Ipshita Majhi]

Hi,

I am trying to plot 12 plots in one panel. Each column with 4 plots and
three columns like that. Here is the code, I would be grateful if you could
tell me where the error is. Thanking you in advance

; Concepts illustrated:
;   - Specifying how many plots to draw in each row
;   - Left-justifying and centering paneled plots
