Dear ncl-team
I'm try to do a multiplot with 3 plots of a 2dfileds xz with 'gsn_csm_contour'
but I have this warning:

the colormap don't span beetwen the values that I fixed for my 3 plots but there are part of the pannel color which is Black.
How can I remove the black color?
the script that I'm using is the follow:
nnest = dimsizes(nz(:))
plot = new(nnest,graphic)
bdybox = new((/nnest,5/),graphic)
;CenterString= (/"Model Nest1","Model Nest2","Difference"/)
