Thanks to everyone for the feedback, I actually tend to agree that the use
of two different y axes in the same plot should be discouraged. Sometimes
it's just too convenient...
In the end, I used `Geom.subplot_grid` with a `Geom.bar` plot which worked
fine. However, it only worked with
Somehow, I didn't find the reasoning in that particular example very
convincing. The real problem in that example---which the post completely
ignores---is that neither of the axes starts at 0. (The zeros should also
align between the two axes.) I can't see the objection to displaying the
I'd like to replicate the behavior of matlab's `plotyy` in Gadfly, i.e.,
I'm trying to plot data with very different `y` axes but the same `x` axes
on the same plot, any idea of how to get this done? `layer` always seems to
use the same base `y` axis.
Thanks for any pointers,

and intentionally not supported in most grammar of graphics
implementations. See, for one recent post I have handy:
