Unfortunately, the capability is currently unavailable in ggplot2 and is unlikely to ever be available because I believe it is a fundamentally inaccurate means of presenting data. However, in the next version it will be much easier to created faceted displays with varying scales, which should be a better solution for many of these types of problems.
