[ncl-talk] gsnPanelMainPosYF

[Adam Phillips]

Hi Laura,
The behavior you described puzzles me as well. A developer will have to
speak to that. As an alternative, you can completely get around the issue
of using gsnPanelMainPosYF with a call to gsn_text_ndc:
resP = True
resP at gsnFrame = False
....
gsn_panel(wks,plots(0:3),(/nrows,ncols/),resP)
txres = True
txres at txFontHeightF = 0.018
dum = gsn_add_text(wks,"DECEMBER 2015 - INCIDENCE OF SHALLOW CONVECTION
",0.5,0.95,txres)
frame(wks)
