Does anyone know of a simple way to rotate a normal line plot through 90
degrees, such that the x-axis is now in the y direction and the y-axis in
the x direction.
cheers,
S

That's what I was looking for Andry. The simplicity speaks for
itself...especially when I just spent the last 1/2 hour working with
!P.T and T3D (and it still looked a lot worse than your solution).
Thanks!

Might help as a starting point
b=randomu(n,10)
x=indgen(10)
window, 0 & plot, x, b
window, 1 & plot, b, x, xrange= [1,0]

You are asking too much of !P.MULTI. It needs you to
leave *everything* up to it. When you throw T3D in
there, you totally screw up the system variables
!P.MULTI requires. You will want to position your
plots with the position keywords and NOERASE. Leave
!P.MULTI out of it. :-)
Something like this:
data = fix(randomu(seed, 100) * 10)
plot, data, position=[0.1, 0.1, 0.6, 0.9]
T3D, /RESET, TRANS=[0.0, -1.0, 0.0], ROT=[0,0,90]
plot, histogram(data), /noerase, $
position = [0.1, 0.1, 0.9, 0.3], /T3D
I couldn't find Liam's Hist_Plot. Have you seen my
HistoPlot?
IDL> Histoplot, Fix(RandomU(seed, 200)*20), $
POLYCOLOR=['charcoal', 'steel blue'], /FILLPOLYGON
