install.packages("vcd")
library(vcd)
counts<-table(Arthritis$Improved,Arthritis$Treatment)
counts
barplot(counts,main="Stacked Bar Plot",xlab="Treatment",ylab="Frequency",col=c("red","yellow","green"),legend=rownames(counts))

画条形图的时候图例的位置不好，和条形产生了重叠，请问用什么语句进行图例位置的重新排布

1. barplot(counts,main="Stacked Bar Plot",xlab="Treatment",ylab="Frequency",col=c("red","yellow","green"), xlim = c(0, 3.2))
   
2. legend(2.5, 42,fill=c("red","yellow","green") ,
   
3.        legend=rownames(counts))

复制代码

试试

barplot(counts,main="Stacked Bar Plot",xlab="Treatment",ylab="Frequency",col=c("red","yellow","green"))
legend(locator(1),c("None","Some","Marked"),fill=c("red","yellow","green"))

刚用了这种解决方式，发现没有你的好，非常感谢哈
