R plot y轴数字刻度改变

axis里的las功能
注意看y的值
原代码

plot(1:4,axes = FALSE)
x.lab = c("CHINA","ANHUI","HEFEI","USTC")
axis(1,1:4,x.lab)
axis(2)
box()
grid()

plot(1:4,axes = FALSE,las = 1)
axis(1,1:4,x.lab,las = 2)
axis(2,las = 1,xlab = "dd")
title(main = "Cici",col.main = "red")
box()
grid()

注意看y刻度以及标题

另一个函数text
text(x = c(1:length(instanceSize)),par(“usr”)[3]-0.2,labels = instanceSize,srt = 45,xpd = TRUE)
其中srt 表示角度
