Re: Plot Placement on the Page and the Margins

Hi John,

By default, NCL wants to draw its graphics to a unit square. This
doesn't bode well when you want to send the output to non-square
output, like an 8.5" x 11" page.

To help get around this, we have created a special resource called
"gsnMaximize" that works with any of the main gsn_xxxx plotting
routines. Set this resource to True:

    res = True
    res_at_gsnMaximize = True
    res@.... ; set other resources as desired
    plot = gsn_xxx_yyyy(...) ; call the plotting routine of choice.

This resource will cause your graphics to be maximized in size of
the output you are using. It will rotate your plot 90 degrees if this
is the best way to maximize the output.

I'm not sure you can completely get rid of margins, however. If your
plot is a perfect square, and you really don't care about any
titles, tickmarks, labelbars, etc, outside of the plot, then you can
maximize its size in the unit square by setting:

    res_at_vpXF = 0.0
    res_at_vpYF = 1.0
    res_at_vpWidthF = 1.0
    res_at_vpHeightF = 1.0

and then don't set gsnMaximize.

Let me know if either of these methods don't work for you.
