Constrain the domain so that the desired area is shown. This can be done by limiting the lat/lon dimension environment, by using 'set mpvals', or both.

<div><br></div><div>3. call 'q gxinfo' and parse the output to get the size of the frame. E.g. </div><div><br></div><div><div><font face="Courier"><span style="font-size:13px">ga-> q gxinfo </span></font></div>
<div><font face="Courier"><span style="font-size:13px">Last Graphic = Contour</span></font></div><div><font face="Courier"><span style="font-size:13px">Page Size = 11 by 8.5</span></font></div><div><font face="Courier"><span style="font-size:13px">X Limits = 0.5 to 10.5</span></font></div>
<div><font face="Courier"><span style="font-size:13px">Y Limits = 1.25 to 7.25</span></font></div><div><font face="Courier"><span style="font-size:13px">Xaxis = Lon Yaxis = Lat</span></font></div><div><font face="Courier"><span style="font-size:13px">Mproj = 2</span></font></div>
</div><div><br></div><div>Note the The display is 10 inches in X (10.5 minus 0.5) and 6 inches in Y (7.25-1.25). This means your plot has an aspect ratio of 1.6667. </div><div><br></div><div>4. Quit grads, then restart with "grads -a 1.6667" instead of using -l or -p. </div>
<div><br></div><div>5. check the 'q gxinfo' output again: </div><div><br></div><div><div><font face="Courier"><span style="font-size:13px">ga-> q gxinfo </span></font></div><div><font face="Courier"><span style="font-size:13px">Last Graphic = Contour</span></font></div>
<div><font face="Courier"><span style="font-size:13px">Page Size = 11 by 6.59987</span></font></div><div><font face="Courier"><span style="font-size:13px">X Limits = 1.25011 to 9.74989</span></font></div><div><font face="Courier"><span style="font-size:13px">Y Limits = 0.75 to 5.84987</span></font></div>
<div><font face="Courier"><span style="font-size:13px">Xaxis = Lon Yaxis = Lat</span></font></div><div><font face="Courier"><span style="font-size:13px">Mproj = 2</span></font></div></div><div><br></div><div>6. Note the different page size. Use these numbers to change your parea command:</div>
<div>'q gxinfo'</div><div>psz=sublin(result,2)</div><div>xsz=subwrd(psz,4)</div><div>ysz=subwrd(psz,6)</div><div>'set parea 0 'xsz' 0 'ysz-0.0001</div><div>Rounding issues force me to reduce the y size by a tiny bit in order to avoid the message: 'parea values beyond page limits.' </div>
<div><br></div><div>7. Now redo your display and you'll see that your plot fills the entire window. Here is a sample:</div><div><br></div><div><img src="cid:8648D837-6C7E-4D6D-8EFF-3AD933829F55@SME" height="413" width="632"></div>

I will take a look at the mpvals. I know you can zoom in by reducing the lat/lon pairs - guess I should have said I want that full domain plotted :P</div><div class="gmail_extra"><br clear="all"><div><div dir="ltr">

<div dir="ltr">William,<div>You can "zoom in" by reducing the lat and lon ranges before you display the variable. Also, try using 'set mpvals...' (see <a href="http://grads.iges.org/grads/gadoc/gradcomdsetmpvals.html" target="_blank">http://grads.iges.org/grads/gadoc/gradcomdsetmpvals.html</a>) to specify which areas you wanted included in the plot.</div>

Usually the extra white space is used for text and such, but in my case I want to fill the entire plot area (or most of it) and get rid of as much white space as possible. I have played around with various values for vpage and parea as well as the image size output (so it is NOT distorted), and it just seems to re-scale the image, and not let me fill the entire area. Ideally it would be nice to set your parea>vpage, but that's not possible. I have posted an example image below. I made the background black to show you all the excess space. Now obviously the image is not rectangular, and I have cropped the left and the right side, but how can I get rid of that excess on the top and bottom without using an external utility to crop it after the fact?</div>
