[ncl-talk] Issue with ploting of irregular txt/nc file

[Guido Cioni]

Amit,
I suspect that your NCL installation has something wrong. I was able to
plot the data easily by using your script (see attachments).
Please try to resolve your local installation problems since the script is
perfectly working.

P.S. I assumend that the 3 text files that you sent were part of the same
file that you splitted because of the attachment dimension, so I merged
them back together before plotting.
