[ncl-talk] 4 panel plot color error message

[Rashed Mahmood]

The colors variable is commented in the script. There are other possible
issues: colors1,2,3 are not defined and only colors3 is used in the fourth
plot while the first three plots use colors. But still the colorbar
procedure is being invoked for colors0, colors1, colors3 etc.
