我正在尝试做一些散点图，但我没有正确地得到馅饼。我用这个：
pie<-ggplot()+geom_scatterpie(aes(x=month, y=2, group=type, r = TotalOvershootings/5),
cols= c("IndustrialCompound", "Pharmaceutical", "Pesticide"),alpha= 0.7, color=NA,
data= counts)
我得到了这个：
每次我改变 r，馅饼只会变薄。如果我离开r = TotalOvershootings，我会让大馅饼重叠。
我能做些什么改变才能把馅饼做好？每次更改 r 时，我都希望看到圆形饼图而不是椭圆形。
