This appears to work great. However, is there a way to programmatically to extract the bin size that ggplot selected in order to be able to change this for multiple data sets? Similarly, is there a way to determine the number of count in each bin that ggplot establish? I wanted to change the axis a bit based on the count size, but I needed to do it programmatically give the large number of samples. For the example below, it would be something like the following: ggplot(diamonds, aes(x=price, fill=cut)) + geom_bar(position=position_dodge(width=default_ggplotbinwidth*0.75), binwidth=default_ggplotbinwidth) + ylim(0, ggplotmaxcount*1.1) I would like to have access to the calculated ggplotbin and ggplotmaxcount for the data set. Thank you again for your help.

It would be nice if a small space could be added. You can do something like this: ggplot(diamonds, aes(x=price, fill=cut)) + geom_bar(position=position_dodge(width=400), binwidth=500) Hadley -- http://had.co.nz/ [[alternative HTML version deleted]]
