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)

f(x)

counts <-------- ---------> x

I want count=0 to be on the shared y-axis. Perhaps log of counts as

well...so normal histogram options.

Thanks.
