You are telling it to shade all values above 0.7, but there are no values above 0.7, so you end up with no shading. If you use a smaller value like 0.6, you will get some yellow contours.</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">--Mary</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">

I am trying to use gsn_contour_shade to plot a variable that varies<br>
betwen 0.1 and 0.7, following the bottom of the script coneff_13.ncl.<br>
Unfortunately, I cannot make the area of values greater than 0.7<br>
filled with color 150 and I am not sure why. My script is in<br>
/glade/p/work/laura/GFconvection/MPAS.GFconvection-v3.3.mynn/rotation.50_3.overSouthAmerica<br>
<br>
but basically, it contains the lines:<br>
<br>
;SET RESOURCES:<br>
<br>
res = True<br>
res@gsnDraw = False<br>
res@gsnFrame = False<br>
res@gsnMaximize = False<br>

res@cnLevelSpacingF = 0.1<br>
<br>
;res@mpOceanFillColor = "lightcyan"<br>
;res@mpInlandWaterFillColor = "lightcyan"<br>
;res@mpLandFillColor = "gray75"<br>
<br>
wks = gsn_open_wks("pdf","schematicRefineMesh.limited")<br>
gsn_define_colormap(wks,"wh-bl-gr-ye-re")<br>
<br>
plot = gsn_csm_contour_map(wks,ConvF_meshD,res)<br>
<br>
opt = True<br>
opt@gsnShadeHigh = 150<br>
plot = gsn_contour_shade(plot,ConvF_meshD@_FillValue,0.7,opt)<br>
<br>
draw(plot)<br>
frame(wks)<br>
<br>
<br>
A few hints would be greatly appreciated. Thanks,<br>
