Hello,
I'm trying to make a plot that is oriented at 90degrees to another plot on the same page.
A command something like:
plot,time,variable,position=position,orient=90
would do the trick - only "orient" isn't a keyword.
Any idea how this might be done?
Thanks greatly.
Phil

Just swap your variables:
t= LINDGEN(50)-25
x = t^2
p = PLOT(t, x, LAYOUT=[2, 1, 1])
p2 = PLOT(x, t, LAYOUT=[2, 1, 2], /CURRENT)

This works for most plots but won't if you are using BARPLOT() or creating a filled histogram plot. David Fanning's CGHISTOPLOT for direct graphics has a /ROTATE keyword (with an example in his plot gallery http://www.idlcoyote.com/gallery/) to rotate a filled histogram. Internally his program has to use a lot of calls to PLOTS to emulate a rotated filled histogram. --Wayne

D'oh! I can't believe I didn't try that!
Thanks Phillip (and wlandsman) for your replies.
In this instance swapping the variables (with a little jiggery pokery) works just fine.

Good call Wayne. But, Barplot does have a horizontal property that rotates, i.e. produces horizontal bars, similar to David's cgHistoplot:
x = randomn(1l, 1000)
h = HISTOGRAM(x, BINSIZE=0.1, LOCATIONS=loc)
bp = barplot(loc, h)
bp.horizontal = 1
