Re: plotting ship wind vectors onto a multi-panel map

The only way to "panel" plots that contain wmxxxx calls is to draw them individually using vpXXXX resources to resize them and place them on the page.

It sounds like you've already found the example that shows how to do this, and I'll mention it here for other folks.

Please see weather_sym_5.ncl at:

http://www.ncl.ucar.edu/Applications/weather_sym.shtml

Each plot is sized using the same size:

  mpres@vpWidthF = 0.42
  mpres@vpHeightF = 0.42

and then each plot is positioned using different values for vpXF and vpYF, which specifies the position (in NDC coordinates, 0 to 1) of the upper left corner of your plot:

  mpres@vpXF = 0.06
  mpres@vpYF = 0.94

We've added a ticket for this to hopefully get something in for V6.2.0.

I can plot the vectors onto a 1panel plot by using gsn_contour_map for the background and calling draw and then putting the vectors on top using wmvecmap. I have seen the example where a 4panel plot is created using viewport params and plotting each frame. Is there a way to do this using gsn_panel? Thanks
