Re: Triangular meshes

Thanks for your help.

Another question: Is it possible in ncl to set up the X-axis to
have dates like
   2007/11/15 up to 2007/12/15
or
  11/15 11/25 12/05 12/15

Matlab allows this but none of the examples shown in
http://www.ncl.ucar.edu/Applications/gsn_xy.shtml
show such a behavior. The nearest there is is with
01OCT ---> 30OCT

Best,

  Mathieu
