Although I do think ggplot2 does a superb job of elegant data
visualization; I am not sure any graphics package will do what you
want. I suspect you will first have to do some work binning your
data, and then plot in your package of choice.
In the situation that you have described, I do not believe your two
criteria can be met. Having x bins of equal size seems prohibitive of
having equal number of points in each, when values are highly
Just as a heads up, for this specific of a task, I would expect you
will spend a few hours more than you already have. If you are willing
to be a bit more flexible in your requirements, there are various
binning algorithms in ggplot2 and other packages you could use to bin
x valus, and then plot those against y quantiles.
You are more likely to get a clear answer from the list if you can
provide some sample data and perhaps a few example graphs showing what
you hope to achieve. An easy way to provide some sample data is using
the dput() function and then paste the output into your (plaintext
