overlaying histogram, different y axis

Rooters,

I am trying to overlay two histograms with the same x-axis but
very different y-axes. I want to put the different y-axes on the
left and right hand sides.

I have two difficulties in achieving this:

1) gPad->SetTicky() does not exclusively put a scale on the RHS but is
always in addition to the scale on the left.

2) gPad->SetFillType(4000) while making the pad transparent doesn't make
the histogram within the pad transparent.

Any insights or alternative ways ?

Pete
