Hi Jim,

I have a NG solution. Though it uses less code than OG, I had to think
about it a bit (NG are still much newer to me than OG). I also had to
rely on the undocumented TEXTUPDIR property to flip the labels on the Z
axis (thanks, CT!). Please give this a try:

n1 = 200
n2 = 500
image = dist(n1)
z = findgen(n2)
phi = gaussian_function(n2/10, width=n2)

w = window()
w.refresh, /disable

; Set up 3D axes and phi plot.
p = plot3d(z*0.0+n1, phi*n1, z, axis_style=2, /current, $
xrange=[0,n1], xtitle='X', ytitle='Y', ztitle='Z')
p.rotate, 30, /zaxis
p.rotate, 90, /xaxis

; Hide obscuring axes.
to_hide = 'axis' + strtrim([3, 4, 6, 7, 8, 9, 10, 11], 2)
foreach axis, to_hide do p[axis].hide = 1

; Make phi axis.
phiaxis = axis('y', location=[max(p.xrange), 0.0, max(p.zrange)], $
textpos=1, title='$\phi$')
phiaxis.tickname = $
string(float(phiaxis.tickname)/n1, format='(f4.2)')

; Display image.
g = image(image, overplot=p, transparency=20)
g.zvalue = 200

; XXX: I got help in uncovering TEXTUPDIR. Should it be exposed?
p['zaxis'].setproperty, textupdir=[0,0,-1], /undoc

w.refresh
