更改数据在饼图上的位置

Question

使用下面的代码，我得到了饼图。 "Mon" 从饼图的中间开始。我想让 "Mon" 位于饼图的顶部。有什么方法可以从顶部（星期四的地方）和星期二（星期三的地方）等开始"Mon"

B <- c(2, 4, 5, 7, 12, 14, 16)
pie(B, main="My Piechart", col=rainbow(length(B)),
labels=c("Mon","Tue","Wed","Thu","Fri","Sat","Sun"))

Answer 1

您可以将饼图设置为顺时针方向。

pie(B, main="My Piechart", col=rainbow(length(B)),
   labels=c("Mon","Tue","Wed","Thu","Fri","Sat","Sun"), clockwise = T)
