在ggplot2中,可以通过theme()函数来更改图例的大小。具体来说,可以使用legend.key.size参数来调整图例的大小。该参数接受一个数值,表示图例的大小,单位为pt(点)。较大的数值会...

在ggplot2中,我们可以通过theme()函数中的legend.key.size参数来调整图例的大小。这个参数接受一个长度值作为参数,表示图例中图例键的大小。 ggplot(mtcars,aes(x=hp,y=mpg,color=factor(cyl)))+geom_point()+labs(title="汽车马力与油耗关系图",x="马力",y="油耗",color="汽缸数量")+theme_minimal()+th...
ggplot is one of the most famous library in R and I use it very ofen in daily workflow. But there are three topics I seldomly touch before: legend, label and font size. One reason is that they are not a necessity in out plot. But I believe it is good to be packed in our back...
