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
