barplot：如何获取 y 轴和框外的 y 轴标签，用 box() 创建？

Question

条形图在 PDF 文件中看起来很奇怪。代码：

pdf("fileName2.pdf", width=100, height=75)
par(resetPar())
par(mar=c(30, 150, 7, 7), lwd=2)
barplot(as.numeric(c(2, 4, 1, 6)), col = c("lightblue"), main="Bar plot",
        names.arg=c("This is \nbar 2...1","This is bar 2...2",
        "This is bar 2...3","This is bar 2...4"), , xpd=TRUE, las=1, lwd=3,
        horiz=TRUE, axes=TRUE, axis.lty=1, space=1, cex.axis=22, cex.names=22)
box(which="plot", lty="solid")#lty = '1373'
dev.off()

问题：如何在框外获取 y 轴（这里是 x 轴，因为 horiz=TRUE）的标签（1 到 15）？

Answer 1

您的 pdf 非常大，因为宽度和高度是以英寸为单位指定的。您的 cex 参数也很大。您的参数较小的代码绘制一切正常：

pdf(fileName2.pdf",width = 12) par(mar=c(4,10,4,1),cex=2, lwd=2)      
barplot(as.numeric(c(2, 4, 1, 6)), col = c("lightblue"), main="Bar plot",
names.arg=c("This is \nbar 2...1","This is bar 2...2", 
"This is bar 2...3","This is bar 2...4"), las=1,horiz=TRUE, axes=TRUE) 
box(which="plot", lty="solid") 
dev.off()
