violin - like plots for bivariate data

sounds like bivariate density contours may be what you're looking for.

From: Eric Nord
I'm attempting to produce something like a violin plot to 
display how y
changes with x for members of different groups (My specific 
case is how
floral area changes over time for several species of plants). 
I've looked at
panel.violin (in lattice), which makes nice violin plots, but 
is really set
up to work on a single variable - the area trace represents 
the frequency of
each value of x for each group.

I'm wondering if anyone is aware of a function to do this?

I can imagine how to accomplish this using polygon, but I 
will admit I'm not
sure what the best way would be to smooth the data. That said, I would
prefer not to reinvent the wheel!

Thanks in advance for any wisdom you can share!

Eric
