[ncl-talk] SST plot showing a blank map on Ubuntu machine

[Rick Brownrigg]

Hi Tan,

I don't know offhand what the issue is.  Can you reproduce the exact same
plot on your linux machine as the one produced on your Mac, ie., the first
plot, without introducing *any* changes in color scale?

I ask, because looking at the span of values between the first and seconds
plots, virtually none of the values in the first plot would show up in the
second (although I'd expect at least a small amount of color in the 30-35
range).

The RANGS issue would seem to be a different matter -- a SEGV is never
good. Perhaps we can talk about this one offline if its important to you.

Rick
