Hi,
I want to do a contour plot with red contour for positive value and blue for negative which I manage to make:

levelspos=0+indgen(5)*2
cgcontour, modifcoef_Solar,moi,Zproxy, ystyle=1, Levels=levelspos, $
ytitle='Altitude (km)',yrange=[20,40],xtitle='Month'
levelsneg=-8+indgen(4)*2
cgcontour, modifcoef_Solar,moi,Zproxy, ystyle=1, Levels=levelsneg, $
ytitle='Altitude (km)',yrange=[20,40],xtitle='Month',/overplot

There is NaNs in the modifcoef_Solar matrix and I would like to make them appear on the plot as a gray shaded area.

Do you have any ideas ?

Thank you for your help
