More like a quantile regression plot.

I'm not aware of it if there is. But I agree that it can be a very
informative display of data. I do such plots on data structures
generated using tapply with age, sex categories and quantile() to
generate a value. It gets kind of hairy with the list structure that
results but if you have a more simple data situation it will probably
be more straightforward, and you should post it.

And I already said that.
