Integer axis marker

Mary,

Do you mean res@tmYLFormat = "f" will produce
axis marker without decimal?

I do not want to have float with decimal.

Thanks.

Yongzuo

Hi Yongzuo,

In the future, if you post to ncl-talk, would you change the subject
so that it includes a more meaningful subject, other than "ncl-talk
Digest". This especially helps when we archive the messages.

To get integers on your Y axis, you need to use the tmYLFormat
resource. Dave Brown created a nice example awhile back, showing how
to use different formats. See example 8 at:

http://www.ncl.ucar.edu/Applications/tickmarks.shtml#ex8

In your case, I believe you want:

    res@tmYLFormat = "f"
