将轴刻度线标签添加到堆积的条形图

Question

我有一个用于六个人的表现的数据集。 我想显示“最低”和“目标”效果-在此示例中分别为100和140。

require("ggplot2")
stones<-c("Mick","Keith","Brian","Bill","Charlie","Ronnie")
rMat<-data.frame(c(rep(100,6),rep(40,6),20,21,27,46,138,168),
        c(rep(1:6,3)),c(rep(stones,3)))
colnames(rMat)<-c("X1","X2","X3")
colors <- c("white","#F2F2F2","#E5E5FF", "white","#F2F2F2","#CCCCFF", "white","#F2F2F2","#B2B2FF","white","#F2F2F2", "#9999FF", "white","#F2F2F2","#7F7FFF","white","#F2F2F2","#6666FF")
gp<-ggplot(NULL,aes(X2,X1),label=rROC[,1])+theme_bw()
gp<-gp+geom_bar(data=rMat,stat="identity",fill=colors,colour="gray")
gp<-gp+coord_flip()
gp<-gp+ylab("Performance")+xlab("")
gp<-gp+scale_x_discrete(labels=rMat[,3])
gp

我已将数据每人分成三行（从0到最小值，到目标的最小值，然后是其余部分。

y轴刻度标记超过六个，结果名称不匹配（例如，罗尼（Ronnie）的表现最高，而不是米克（Mick）。

我以前每人一行（带有工作标签），像这样：

perf<-c(160,161,167,186,278,308)
stones<-c("Mick","Keith","Brian","Bill","Charlie","Ronnie")
rMat<-data.frame(perf,c(1:6),stones)

但是，我无法像上面的示例一样拆分条形图。 请任何人提出如何使标签和分隔条起作用的建议吗？

谢谢

像这样吗

pmin <- 40
pmax <- 100
stones<-c("Mick","Keith","Brian","Bill","Charlie","Ronnie")
p    <- c(20,21,27,46,138,168)
gg   <- data.frame(stones,p)
gg$stones <- factor(gg$stones, level=unique(gg$stones))
gg$status <- ifelse(gg$p<pmin,-1,ifelse(gg$p<=pmax,0,1))
ggp <- ggplot(gg)
ggp <- ggp + geom_bar(aes(x=stones, y=p, fill=factor(status)),stat="identity")
ggp <- ggp + geom_hline(yintercept=pmin, linetype=2, colour="red")
ggp <- ggp + geom_hline(yintercept=pmax, linetype=2, colour="blue")
ggp <- ggp + scale_fill_discrete("Status", labels=c("Below Min","Within Range","Above Max"))
ggp <- ggp + labs(x="",y="Performance")
ggp <- ggp + theme_bw()
ggp <- ggp + coord_flip()
ggp
