Easy, order the factor as you want it displayed. See ?factor

Please do try searching or reading basic documentation before emailing
the list. Here is a good place to start:
Hadley also has a good book on using ggplot2 that would be quite
instructive. Finally, note that ggplot2 has a dedicated mailing list
on google that is a better place to post than R-help for ggplot2
There are several ways to accomplish what you want. You show an
image, but have provided no reproducible example nor code. From your
example image, I am guessing you have somehow supressed the default
axis labels and tick marks, but without any indication of how you
created the plot, it is difficult to provide a simple, "do this".
