NCL and gsn_panel

if you do not use this software, disregard:

mary haley recently made a change to gsn_panel that effected the way
compressed panel plots function.

gsn_panel assumes that all the plots are the same size. When you try to
panel plots of different sizes, unexpected (unexplained) results can
occur. things like reference vectors, labelbars, tickmark labels, etc
change the size of a plot signficantly as far as panel goes.

when gsn_panel first came out, mary selected the first plot in the plot
array as the size model. This allowed plots such as
http://www.cgd.ucar.edu/csm/support/CSM_Graphics/Images/panel_7_lg.gif
to be really compressed. the first plot is smaller than the last plot
which has tickmark labels.

unknown to us all, mary recently changed gsn_panel so that the size model
became the largest plot. she did this in antipation of some other
enhancements she is planning. This change resulted in the example above
having too much white space between the figures (space was allocated for
the tickmarks on the largest plot). White space is often unacceptable when
submitting figures for publication.

SOOOO: mary has changed gsn_panel back to the original configuration.

those of you on ncar systems should have access to this change by the end
of the day.

those of you who downloaded NCL can decide whether to upload this change.

Mary is working on adapting gsn_panel so that it can intelligently handle
plots of different sizes, but this is a non-trivial change and will take
some time.

regards,

sylvia
