我已经看到了有关此主题的另一个问题,但我仍然无法更改 ggplot 中分组条形图的颜色。它为我提供了蓝色刻度,但我想要绿色刻度。我对 ggplot 非常陌生,可能遗漏了一些明显的东西。
这是我的一些代码:
TCplot=ggplot(mTCdf,aes(x=types4,y=TCs,group=years3,color=years3))
+geom_bar(aes(fill=years3),stat="identity",position="dodge",color="black")
mTCdf$types4=factor(mTCdf$types4,levels=c("Single Year Lease","Multi-Year Lease","Permanent"))
levels(mTCdf$types4) ###just to get my labels in my desired order
TCplot=TCplot+ggtitle("Total Costs by Transaction_Type")
+theme(plot.title=element_text(lineheight=.7,face="bold"))
+xlab("Transaction Type")
+ylab("Costs ($)")
library(scales)
TCplot=TCplot+scale_y_continuous(labels=comma)
TCplot=TCplot+scale_fill_manual(values=c("#66FF22","#33FF22","#33EE22","#33DD22","#33CC22","#33BB22","#33AA22","#339922","#338822","#337722","#336622"))
TCplot=TCplot+scale_fill_manual(values=c("#66FF22","#33FF22","#33EE22","#33DD22","#33CC22","#33BB22","#33AA22","#339922","#338822","#337722","#336622"))
错误:提供给离散刻度的连续值!!!啊!
***有人可以帮我应用绿色渐变吗?谢谢!!
