[ncl-talk] gsn_csm_streamline_scalar* functions

[Alan Brammer]

Mary,

Having just finished my wild goose chase, here are the answers to your
questions.

** Long story short, streamlinePlotClass wasn't supported by gsn_panel. My
work around caused problems. Here's edited versions of gsn_panel so
streamlinePlotClass is supported.  **


The problem I was having with panelling was because I was drawing one plot
with lbLabelBarOn = True.  This was throwing off the dimensions and I think
is a known thing. No big deal I should just use gsnPanelLabelBar = True.
Well here was the problem, when panelling the supported
gsn_csm_streamline_map with stMonoLineColor = False, therefore with
coloured streamlines, gsn_panel says it's an unsupported type and will
ignore the label bar request.   Hence why I was forcing one of the plots to
have the label bar.  I don't like having to draw it myself.


So, because I wanted the ability to panel my new gsn_csm_streamline_scalar*
functions as well as the supported gsn_csm_streamline_map functions. I've
have gone through and edited gsn_panel_return and also had to add
"streamlinePlotClass" to get_plot_not_loglin().


Attached below are a simple script to first identify that gsn_panel will
ignore a labelbar request from the gsn_csm_streamline_map() then load my
edited versions and show that it now works.


Some simple data attached as well.
