Legend on bottom, two rows wrapped in ggplot2 in r

Question

Rdates <- c(\"2007-01-31\",\"2007-02-28\",\"2007-03-30\",\"2007-04-30\",\"2007-05-31\",\"2007-06-29\",\"2007-07-31\",\"2007-08-31\",\"2007-09-28\",\"2007-10-31\")         


        

Answer 1

The solution above is presented for a single aesthetic. In some cases, you may want to wrap the legend into rows instead of columns across different aesthetics. For posterity, this is shown below.

library(ggplot2)

ggplot(diamonds, aes(x=carat, y=price, col=clarity, shape=cut)) +
  geom_point() +
  theme(legend.position="bottom")

The legend is cut off below:

To wrap the legend using rows, we specify legend.box="vertical". Below, we also reduce the margin for compactness.

ggplot(diamonds, aes(x=carat, y=price, col=clarity, shape=cut)) +
  geom_point() +
  theme(legend.position="bottom", legend.box="vertical", legend.margin=margin())
