[ncl-talk] Paneling overlaid plots

[Tabish Ansari]

Hi,

I just solved it by replacing:
gsn_panel(wks,(/plot1,plot2,plot3/),(/3,1/),resP)
with
gsn_panel(wks,(/plot1(0),plot2(0),plot3(0)/),(/3,1/),resP)

Seems like all the information is pasted onto the 0th plot so it's
sufficient to just plot that.

Cheers,

Tabish
