Is it possible to have a figure with two-plots such that....
f(x) is plotted against x on axis 1 (on the right)
histogram of f(x) is plotted horizontally (on the right) sharing
the y-axis of axis 1
(sorry, this is proportional font, ascii art)
counts <-------- ---------> x
I want count=0 to be on the shared y-axis. Perhaps log of counts as
well...so normal histogram options.
