  • Here changing the length of the legend title appears to affect the justification of the legend text: ggplot(iris, aes(y = Sepal.Width, x = Petal.Width)) + geom_point(shape = 21, aes(fill = Species)) + guides(fill = guide_legend(title.position = "top", title.hjust = 0.5)) + scale_fill_manual("A really, really...

  • From the code below, the arguments `hjust` and `vjust` in the `theme(legend.title)` do not do anything (at least on my machine). The two plots produced from both `ggplot()` calls are the same.

My setup is Mac OS 10.7.3, Python 2.7, R 2.14.
"How to change the order of legend labels" is a question that gets asked relatively often on ggplot2 mailing list.
