ggplot中的错误？ 还是需要一个选项才能使其正常工作？

Question

如果x_coordinates的值从左到右增加，则该图是正确的。 如果其中一个值的顺序不正确，则绘图不正确。

请使用x = Vn_correct运行，将给出预期的图。 并使用x = Vn_incorrect运行，将给出校正后的图

library("ggplot2")

  In<- c(0.00522,0.012,0.019,0.026,0.032,0.0392,0.0463,0.172,0.325,0.462,0.576,0.713)
  Vn_correct<- c(0.89,0.92,0.952,0.963,0.975,0.988,0.993,1.089,1.162,1.218,1.247,1.282)
  #Vn_incorrect<- c(0.89,0.92,0.952,0.963,0.975,0.988,0.993,1.089,1.162,1.218,1.295,1.282)
  df<- data.frame(In,Vn)




ggplot(data=df, aes(x=Vn_correct,y=In))+geom_line()+geom_point()

如上图所示，最后三个点必须从A到B再到C（不是A到C再到B）

Answer 1

问题出在Vn_Incorrect中，交换了最后两点。 1.295在1.282之前。 因此，当您按以下方式恢复订单时，我可以获得正确的输出。

library(ggplot2)
In<- c(0.00522,0.012,0.019,0.026,0.032,0.0392,0.0463,0.172,0.325,0.462,0.576,0.713)
Vn_correct<- c(0.89,0.92,0.952,0.963,0.975,0.988,0.993,1.089,1.162,1.218,1.247,1.282)
Vn_incorrect<- c(0.89,0.92,0.952,0.963,0.975,0.988,0.993,1.089,1.162,1.218,1.282,1.295)
df<- data.frame(In,Vn_incorrect)
Test <- ggplot(data=df, aes(x=Vn_incorrect,y=In))+geom_line()+geom_point()
Test

输出如下。 这就是你想要的吗？
