<tt>You could use "gxeps" to convert the metafile to encapsulated
postscript. This differs from "gxps" in that it trims the excess white
space. <br>
<br>
Also, like Ivan said, ImageMagick software is really useful. The
"convert" command can operate on various file formats. Among its many
options is a "-trim" option to remove excess white space. You probably
would need to use a few other option, though, to control the resolution
and quality of the image. ("+antialias", "-density", "-resize" are few
that I use often on grads images.)<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

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".
