I hope IDL 8.2 doesn't (as I fear with such a complex
system!) introduce it's own set of absurdities. :-)
Cheers,

Yay! I was trying to do exactly the same thing as David last week (over a poky DSL line where I could type faster than
the characters got squirted back via the internets).
I no longer have any hair to tear out when I encounter these type of absurdities. I hope the 8.2 beta test doesn't take
too long.

I checked that this problem is solved correctly in 8.2, where the Erase
method will be available for all NG routines, not just WINDOW.

The Delete method should do this, but it's working perhaps a bit too
literally -- if I delete the plot, the axes remain. I think this is a
bug, but the workaround is straightforward:
w = window()
p = plot(/test, /current)
foreach axis, p['axis*'] do axis.delete
p.delete
c = contour(/test, /current)
