The output from a cgWindow takes on the aspect ratio of the window,
since it assumes you want output that resembles as closely as possible
what you are looking at in the window. So, the simple way to get a
portrait aspect ratio in your PostScript and PDF output is to create a
window with a portrait aspect ratio.
You can either grab the window and muscle it into the correct size, or
you can make it the right size when you create it. Something like this:
cgWindow, WXSize=600, WYSize=800
cgPlot, cgDemodata(1), /AddCmd
Or, something like this:
cgPlot, cgDemoData(1), /Window, WXSize=600, WYSize=800
Note that the latter command only works if there are no cgWindows
currently on the display, since it uses whatever window is "open" or
available, as normal IDL commands do.
I don't have a way currently to resize a window programmatically, but I
will in about five minutes. :-)

Make sure you got today's *afternoon* version. The version this morning
was causing me some trouble after I made a change in cgPS2Raster. I had
to revert back to the original file until I get the problem figured out.
Cheers,
