[ncl-talk] How to show poymarker for each subplot when paneling?

[Rick Brownrigg]

Hi,

I don't know for certain, but it looks like in your loop where you iterate
over  "num_distinct_markers" and call gsn_add_polymarker(), you are
overwriting the variable "dum(j)" each time.  There's this comment in the
docs for gsn_add_polymarker():

The value returned from this function must be assigned to a unique
variable. This is necessary so that the polymarkers "live" for the duration
of the NCL script. This is especially imperative if the call to
*gsn_add_polymarker* is inside a function or procedure. Please see the
examples
<http://ncl.ucar.edu/Document/Graphics/Interfaces/gsn_add_polymarker.shtml#Examples>
section below for more information.

So I *think* maybe you want dum dimensioned as 3 x num_distinct_markers,
and inside the loop the assignment would be:

  dum(j,i) = gsn_add_polymarker(....)

Hope that helps...
Rick
