Hi! I don't know if it can be done in GrADS directly, but if you print
image to file, you can call directly from GrADS script an imagemagick
mogrify command that will shave image. For example, after<br>
<br>
'printim path/to/the/image/image.png'<br>
<br>
call mogrify like this:<br>
<br>
'!/usr/bin/mogrify -shave 20x20 path/to/the/image/image.png'<br>
<br>
where 20x20 are sizes of shaved space from the image borders.<br>

I have to make the image about 3in by 3in and the extra white space
makes the plot even harder to read. I might be able to do this post
process but I would rather get it in GrADS. I was thinking maybe
setting the plot size to be the same size as the page size but....any

<pre style="">John,
I'd use a grads script to return the XY coordinates of the sides of the
plot using "q gxinfo", then use "draw string" to plot labels relative to
the 4 corners. Include something like this to get the X and Y values
of the sides of the plots:
'q gxinfo'
xvalues=sublin(result,3)
yvalues=sublin(result,4)
* xl = plot starts xl inches from left
* xr = plot ends xr inches from left
* yb = plot starts yb inches from bottom
* yt = plot ends yt inches from bottom
xl=subwrd(xvalues,4)
xr=subwrd(xvalues,6)
yb=subwrd(yvalues,4)
yt=subwrd(yvalues,6)
The lower left corner of the plot would be at "xl" "yb". Upper left at
"xl" "yt". Upper right "xr" "yt". Lower right "xr" "yb".
