[ncl-talk] SHAPE FILE PROBLEM

[Rick Brownrigg]

Hi,

It looks like you want to adjust your NDC coordinates for the legend. You
can add this call right before your call to draw:

 drawNDCGrid(wks)

It will help with determining appropriate NDC coords.  (You also have to
add this load command at the top:

  load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl"

If you want nice left-justified labels within the legend columns, you could
add this resource:

   res at txJust = "LeftCenter"


All that said, you may not have enough room in the existing bottom margin
to plot your legend, in which case you'll want to push your map upwards on
the page;  see the examples at

  http://ncl.ucar.edu/Applications/viewport.shtml

for how to adjust the "viewport".

Finally, as for the black line, that's coming from NCL's map database. To
turn it off, I *think* its:


  res at mpOutlineOn = False

I hope that helps...
Rick
