使用R中的matplot更改轴标签

Question

我正在尝试更改matplot中的x轴，但此命令不起作用：

TimePoints=1997:2011
matplot(t(DataMatrix),type='l',col="black",lwd=1,xlab="Anni",ylab="Rifiuti",main="Produzione rifiuti")
axis(side=1,at=TimePoints,labels=TimePoints)

plot我毫无问题地使用了这个。我该如何解决？ 在这里您可以找到对象：https://dl.dropboxusercontent.com/u/47720440/SOF.RData

Answer 1

我通常这样做如下：

1. 完全省略轴。
2. 逐个添加带有所需选项的轴。

在R：

# Add argument axes=F to omit the axes
matplot(t(DataMatrix),type='l',col="black",lwd=1,xlab="Anni",ylab="Rifiuti",main="Produzione rifiuti",axes=F)

# Add Y-axis as is
axis(2)

# Add X-axis
# Note that your X-axis range is not in years but in the "column numbers",
# i.e. the X-axis range runs from 1 to 15 (the number of columns in your matrix)
# Possibly that's why your original code example did not work as expected?
axis(side=1,at=1:ncol(DataMatrix),labels=TimePoints)
