We frequently use direct graphics and !P.MULTI to generate graphics output
where there are multiple plots on multiple pages. It is not hard to make
this work either to the display or to a PS file. When drawing to the display
you can wait for a <cr> before moving to the next page. When creating PS, you
just draw all the plots to a single file. The PS file can then be easily converted
to a multi-page PDF file.
With the new Graphics system, I can see how to draw multiple plots in a single
window, but not how to create multi-page graphics. Is the concept of multi-page graphics
not part of the new Graphics system?
I can see that it could be done by keeping track of the number of plots in a window and
saving the window to a graphics file when full, etc., but the result is then multiple PDF files
rather than a single file.
Am I missing something? Is there an easy way to do what I need with the New Graphics
system, or do I need to stay with Classic Graphics.
Thanks, Ken Bowman

It may be, but I can't see how. The LAYOUT keyword works similarly
to !P.MULTI, but as far as I can tell it only works for
a single window.
If you want to create multi-page PS or PDF documents you will have
to create each page in a separate window, save to the appropriate
file type, and them concatenate the files/pages using SPAWN or something
similar.
Or use Old Graphics (direct graphics).
I would be happy to be corrected if this is wrong.

Hi Paul & Ken,
In IDL 8.0, multi-page postscript files still work fine, just as they
did before.
For the new graphics, we added support for PDF output, but we ran out
of time to do multi-page output. I have some prototype code that adds
this feature, if you're interested in trying it out.
Cheers,
Chris

Besides what David mentioned above, note that you can combine
different layout grids to make non-rectangular multiplots, as show in
one of the examples of the last webinar:
http://groups.google.com/group/comp.lang.idl-pvwave/browse_t hread/thread/a44a227fb6d32cf7/
Also, I am finishing writing a class to provide in the new graphics
functionality like IDLAstro's multiplot does for direct graphics. It
is more flexible than multiplot, allowing to have lines/columns of
different heights/widths, and providing synchronization of axes
properties. It will be out probably sometime this week.

You want to use the LAYOUT keyword in conjunction with
the CURRENT keyword.
IDL> p = plot(loaddata(17), layout=[2,2,1])
IDL> p = plot(loaddata(17), layout=[2,2,2], /current)
IDL> p = plot(loaddata(17), layout=[2,2,3], /current)
IDL> p = plot(loaddata(17), layout=[2,2,4], /current)

I looked up one of the multiple plot examples
in the on-line help. Then, I mucked around
until I figured it out. :-)

Ken,
I am having trouble creating MULTI-PLOT images in the same window with
IDL8.0 . From above, you mention that you can produce multiple plots
on one image with the new 8.0 . Personally, I am struggling to
accomplish this. IDL help menu shows how to do !p.multi using older
releases of IDL, NOT with the newest 8.0 version. It makes no sense to
me to start using a new release, but have to depend on previous
releases to make progress, especially when the things I am trying to
do have been updated in 8.0. For example, you probably noticed the new
method in 8.0 to produce plots p = PLOT(xxxxxxxxxx) and then we can
save the plot by typing P.SAVE ......this to me is VERY easy. But, to
use !p.multi it seems like I need to issue plot commands from earlier
IDL releases. Bummer!
How did you find out to create multi plots on one window in 8.0?
Thank you very much for your time.
cheers,
teddy allen
