[ncl-talk] Plot of constant values

[Alan Brammer]

It'll help everyone solve this by describing how it is not working?  Also
fyi these are resources not functions.


This works exactly as expected for me in 6.2.0 and 6.2.1.


x = new ( (/100,100/), float)
x = 100

wks = gsn_open_wks("X11","ConstFill_wks")

res = True
res at cnFillOn = True                 ;;;;  The contour needs to be filled to
start with, for a constant value to be filled.
res at cnConstFEnableFill = True
res at cnConstFLabelOn = False

plot = gsn_csm_contour(wks, x, res)
