[英]How to increase size of legend in ggplot2
I'm new to the ggplot
plotting library in R
and can't work out how to increase the size of my legend. 我是R
ggplot
绘图库的ggplot
增加图例大小的问题。 I know you can do axis manipulation with theme(axis...)
but I can't find the correct argument to pass! 我知道您可以使用theme(axis...)
进行轴操作,但是我找不到要传递的正确参数!
The code I use to produce the figure is here: 我用来生成该图的代码在这里:
library(ggplot)
library(ggalluvial)
ggplot(data = wrong_cases_all,
aes(axis1 = cae, axis2 = places,
y = freq)) +
scale_x_discrete(limits = c("CAE", "VGG16-Places365"))+
xlab("Model") +
geom_alluvium(aes(fill = freq)) +
geom_stratum() + geom_text(stat = "stratum", label.strata = TRUE) +
theme_minimal()
Does anybody have any tips? 有人有提示吗?

wrong_cases_all <- read.table(header=TRUE, text = "cae places freq
