在geom bar中使用比例尺颜色手册的问题

我的数据如下所示：

AA  Extracellular   Intracellular
A   2.23        5
B   8.6         5
C   13.5        5

rdatamy<-read.table("rat.txt",header=TRUE) # load the File
molten2<-melt(rdatamy,id.vars="AA",measure.vars=c("Extracellular","Intracellular"))#melt
plot2<-ggplot(molten2,aes(x=AA,width=0.3,y=value,colour=variable))+ 
geom_bar(position='dodge',stat="identity") + scale_color_manual(values=c("Intracellular" = 
"cyan","Extracellular" = "gold2"))

代码如下所示：

AA  Extracellular   Intracellular
A   2.23        5
B   8.6         5
C   13.5        5

rdatamy<-read.table("rat.txt",header=TRUE) # load the File
molten2<-melt(rdatamy,id.vars="AA",measure.vars=c("Extracellular","Intracellular"))#melt
plot2<-ggplot(molten2,aes(x=AA,width=0.3,y=value,colour=variable))+ 
geom_bar(position='dodge',stat="identity") + scale_color_manual(values=c("Intracellular" = 
"cyan","Extracellular" = "gold2"))

请帮助我理解这一点。

要更改条形图的颜色，请使用fill=variable和scale\u fill\u手册中所需的值，因为color=variable会更改条形图周围的线条。酷。谢谢这很有魅力
