Hi<

I have 2 histograms ... A and B
A=histogram(a) B=histogram(b)
they have same xrange, but different yrange.

I have the ratio of the n_elements(a)/n_elements(b)

NOW, I want to plot them on top of each other so they
are normalized.
AND, the left y-axis shows A's range,
the right axis shows B's range.

I can achieve most of the objectives if I :
(1) plot A
(2) normalize B
(3) oplot B

the problem is this leaves out B's y-axis.

instead of normalizing B , I want to normalize B's plot.

possible??
