Hi Pedro, What's the problem exactly? You'll need to compute the range yourself, and then use scale_y_continuous as you have below.
(Also you can abbreviate the bar chart plotting command to: qplot(x, y, data=plotdata, geom="bar", stat="identity")) Hadley On 12/11/07, Pedro de Barros <[EMAIL PROTECTED]> wrote: > Dear All (probably Hadley), > > I am now trying to customise some plots using a bar geom. > > I do not want to use the default binning statistic, but rather > calculate the bar heigths separately.
