[ncl-talk] question about gsn_histogram

[Mary Haley]

Xiaoyan,

You sent your email to ncl-talk at ucar.edu, but apparently you are not
subscribed and the message bounced.

You must subscribe to ncl-talk before you can send email to it.  For
details, please see:

http://www.ncl.ucar.edu/Support/email_lists.shtml

Meanwhile, to get your X axes to match, you can explicitly set the
intervals using gsnHistogramClassIntervals.

For an example, see:

http://www.ncl.ucar.edu/Applications/histo.shtml#ex5

If you have more questions, please subscribe to ncl-talk and send your
question to ncl-talk at ucar.edu.

Thank you,

--Mary
