Re: spread color plot in opt@pltColorMap

Antonio,

wkSpaceTime is very limited on what plotting resources it allows you to set. Please see the documentation to see what you can change:

   http://www.ncl.ucar.edu/Document/Functions/Diagnostics/wkSpaceTime.shtml

However, as Dennis stated earlier, you can modify the $NCARG_ROOT/lib/ncarg/nclscripts/csm/diagnostics_cam.ncl script yourself and set any resources you want.

To do this, I first suggest copying the "diagnostics_cam.ncl" script into your own directory:

  cp $NCARG_ROOT/lib/ncarg/nclscripts/csm/diagnostics_cam.ncl .

Then, edit this copy of diagnostics_cam.ncl and search for

procedure wkSpaceTime

Then, search for:

   res = True

After this line, you can add the gsnSpreadXXX resources you want to set.

Finally, in your NCL script, instead of loading:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/diagnostics_cam.ncl"

you want to load:

load "./diagnostics_cam.ncl"
