I think it's IDL's way of looking more "high definition." :-)

Really!? Somehow this doesn't surprise me as much
as I thought it might!
Anyway, too late to worry about it tonight. Thanks
for the programs. They are terrific, as always. :-)
Cheers,
David

David, sometime in the late unpleasantness, IDL started to defaulting
to 640x389 for plot window dimensions. I think you are seeing this
ratio.
If I explictly make a window 640x512, then PXPERFECT and your CGPLOT
both make Postscript graphic pages of the right size ratios.

Well, let's see, I should be measuring the axes
lengths in the display window, which should be,
given their position in the window:
(512 - (512 * 0.15)) / (640 -(640*0.13)
435 / 557 = 0.781
Humm. Weird. :-(

I guess! :-)
I was curious about your PXPERFECT routine, because
I've had my own struggles getting PostScript output
to look like what is on the display. I just ran a
test.
I compared the output of this command:
cgplot, cgdemodata(1), xtitle='Time (Seconds)',
ytitle='Signal Strength', $
position=[0.125, 0.125, 0.95, 0.85], $
title='Experiment 10A3B', output='test.ps'
With this (I think I did this correctly):
thisDevice = !D.Name
ps_extra = pxperfect(/landscape, thick_factor=tf)
set_plot, 'ps'
device, _extra=ps_extra
cgplot, cgdemodata(1), xtitle='Time (Seconds)',
ytitle='Signal Strength', $
position=[0.125, 0.125, 0.95, 0.85], $
title='Experiment 10A3B', thick=tf
device, /close
set_plot, thisDevice
These commands should be duplicating what I would see
in a normal 640 by 512 graphics window:
cgDisplay, 640, 512
I see almost no difference in the character size,
interestingly enough. But I do notice that your
plot is a dfferent size than mine is.
If I print and measure my plot, it is 20x14cm. Your
plot is 18.5x13. These ratios are 0.7 and 0.702.
The ratio of the window is 512/640 = 0.8. Are we
both wrong? :-)
Cheers,
David

Dang, it's a tough crowd in here tonight :-)

Fabulous programs! But, Craig, dear Craig, it's the 21st
century. *Everyone* is using square bracket subscripting now! ;-)
