添加軸勾號標籤到堆積條形圖

Question

我有一個六人表現的數據集。我想顯示「最低」和「目標」表現 - 在這個例子中，分別是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 

我的數據拆分成三行每人（爲0至最低，最低到目標，然後將剩餘部分。

有多於六個y軸刻度標記，並。其結果是，名稱不匹配（例如，羅尼具有最高的性能，而不是米克）

我以前有每人一行（有工作標籤），像這樣：

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，我無法像上面的例子那樣分割條。請任何人都可以建議如何讓標籤和分割條工作？

謝謝

是這樣的？

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
