Hi, is it possible to do a multivariable barplot with ggplot2?

I have something like that:

> df

           LENGTH LAT

091639  10.002   42.26282
091640  30.808   42.26834
091641   21.591  42.31689
091642   22.030  41.53246
091643   22.744  42.01954
091644   12.702  42.67751
091645   39.728  42.06479
091647   63.057  41.25283
091648   19.523  41.01925
091649   13.336  42.46904

091650 8.935 42.80971
091651 25.275 42.50678
091652 9.983 42.89345
091653 9.416 41.15288

> p <- ggplot(df)
> p <- p + geom_bar(aes(x=rownames(df), y=LENGTH), position="dodge",
fill="red")
> p <- p + geom_bar(aes(x=rownames(df), y=LAT), position="dodge",
fill="green")
> p

but the result graphics are overlapping.

Thank for your help
