是否可以在同一个图表中绘制多个 errbar？所以当我这样做时：
x <- c(5.7/6,5.723/6,5.678/6,5.7/6,5.8/6,5.75/6,5.789/6,5.987/6,5.978/6,5.998/6)
y <- c(15,30,45,60,75,90,105,120,135,150)
xplus <- x+runif(10,0.01,0.015)
xminus <- x-runif(10,0.01,0.015)
errbar(y,x, xplus,xminus,type="b",ylim=c(0,1), lwd=2,lty=1)
我想在其中添加另一个 errbar。所以简单地把另一个errbar 不起作用。它覆盖了前一个。希望我能做到这一点吗？
