Re: Making multiple subplots & save the graphics o/p

Hi Welcome to Ferret and the Users List!

I'll point you to topics in the Users Guide where you can read more about
all of your questions, and try to give a quick answer.  I'm sure you've 
found
the on-line Users Guide at
http://www.ferret.noaa.gov/Ferret/Documentation/Users_Guide/current/fer_html.htm

1) this is "viewports, advanced usage"  in the Users Guide index.  You 
want to
define your own viewports, where the limits are proprotions of the plot 
window

yes? define view/xlimits=0,.33/ylimits=0,.5   vll
yes? define view/xlimits=.33,.66/ylimits=0,.5 vlm
yes? define view/xlimits=.66,1/ylimits=0,.5   vlr
yes? define view/xlimits=0,.33/ylimits=.5,1   vul
yes? define view/xlimits=.33,.66/ylimits=.5,1 vum
yes? define view/xlimits=.66,1/ylimits=.5,1   vur
yes? set view vll
...

You might also want to change the aspect ratio of the plot page so the 
viewports
are propotioned nicely.  There are some scripts included with Ferret 
which set up
a plot page and define a set of viewports.  Use the Unix command Fgo to see
these; you might copy the commands from one of them for your own set-up
script.

> Fgo landscape
> Fgo portrait

2) This is under the topic "hardcopy" in the Users Guide.  You can have
Ferret draw a postscript plot using a metafile.  These commands will create
a metafile called metafile.plt  which you can later convert to postscript:

yes? set mode meta
yes? ... plot commands  ...
yes? quit

> Fprint  -o myplot.ps  metafile.plt

3) Here, you need to use the ideas in chapter 6, Customizing Plots.
You will use a PPL command to customize the vector key.

yes? vector/set  u,v
yes? ppl vecset/nouser, -1, -1
yes? ppl vector
