[ncl-talk] Overlay contour on contour

[Roussan]

Hello,
I'm trying to overlay a map, and 2 differents contours.

-Map
-Cloud cover
-Precipitations

I can't achieve that without seting "prec_res at cnFillOpacityF" below 1
(line  98 of my script), but legend colors become untrue.

if I comment "prec_res at cnFillOpacityF" I only can see map and
precipitations,
but no clouds.

I would like to fully plot precipitations over clouds and map,
without alter legends colors.

Thanks in advance for your help.
Ross

 PS : script + grib2 in attachement.
