Legend on bottom, two rows wrapped in ggplot2 in r
Solution 1
You were really close. Try this at the very end:
gg+guides(fill=guide_legend(nrow=2,byrow=TRUE))
Solution 2
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())

Currently have a ggplot2 stacked bar graph setup. Everything works properly now except I am having an issue with the legend. I have put it on the bottom but there are 10 items so some are cutoff (doesnt fit). I tried
guides(fill=guide_legend(nrow=2))
but this puts the labels in a different order (I want to get the first 5 across then the last 5 below. Any suggestions? -
Trevor Nederlof about 8 yearsAh wow cant believe I didnt find that. Thanks for the answer, was banging my head against the desk.

mluerig almost 3 years
byrow=TRUE
should be the default behavior -
Miao Cai over 2 yearsHi there, is there any way we can make the legend of clarity above that of cut? Thank you!

nstjhp about 2 years@MiaoCai Yes look at the order parameter of guide_legend e.g. stackoverflow.com/a/11397958/3275826
