如果我有以下數據,並使用ggplot2
繪製它,我得到:更改複合圖例標題
a <-c(0.3,0.3,0.3,0.3,0.3)
b <-c(1:5,0.9,0.9,0.9,0.9,0.9)
c <-c(1:5,0.5,0.5,0.5,0.5,0.5)
z <-rep(1:5,5)
df <- data.frame(y=c(a,b,c),x=c(z),line=c(rep("1",5),
rep("2",5),rep("3",5),rep("2",5),rep("3",5)))
library(ggplot2)
a <- ggplot(df,aes(x=x,y=y,fill=line,shape=line,group=line)) +
geom_line(aes(linetype=line),size=1) +
scale_linetype_manual(values=c("dashed","solid", "dotdash")) +
geom_point(size=3) + scale_shape_manual(values=c(25,23,21,25,23)) +
scale_fill_manual(values=c("red", "blue", "yellow","red", "blue"))
如果我想指定的傳奇頭銜,我可以做許多事情一樣
a + labs(shape = "MY TITLE HERE") # or
a <- ggplot(df,aes(x=x,y=y,fill=line,shape=line,group=line)) +
geom_line(aes(linetype=line),size=1) +
scale_linetype_manual(values=c("dashed","solid", "dotdash")) +
geom_point(size=3) + scale_shape_manual(values=c(25,23,21,25,23),name="MY
TITLE HERE") +
scale_fill_manual(values=c("red", "blue", "yellow","red", "blue"))
然而,所有的這些選擇打破了複合傳說成其單獨的映射paramters。
如何維護與linetype
,shape
和fill
的複合圖例並更改圖例標題?
相當畢竟簡單,非常感謝你@Andrie –
