Re: Station data: overlay

Hi Jimmy,

It looks like gsn_csm_contour_map_overlay is prototyped to expect 2D
data. I'll have to fix this.

Meanwhile, you can try this as a work-around:

Copy $NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl to your own
directory.

Modify this copy of gsn_csm.ncl and change:

function gsn_csm_contour_map_overlay(wks:graphic,data1[*][*]:numeric,\
                                      data2[*]
[*]:numeric,res1:logical, \
                                      res2:logical)

to:

function gsn_csm_contour_map_overlay(wks:graphic,data1:numeric,\
                                      data2:numeric,res1:logical, \
                                      res2:logical)

Then, load your own copy of "gsn_csm.ncl" instead of the one in
$NCARG_ROOT/lib/ncarg/...

Having said all this, however, I think it might be easier to call
gsn_csm_contour and
gsn_csm_contour_map yourself, and do the overlay. You have more control
over the positioning of the extra plot elements this way.

For some examples, see example #1 on the applications page:
