我正在尝试绘制一个散点图，其中Y轴根据日期字段排序。但是，我只能将A作为一个因素来执行以下操作。有关如何实现这一目标的任何建议吗？

p = ggplot(points, aes(Date, factor(A))) +
    geom_point(aes(colour=factor(A)), size=1.8) + 
    scale_shape(solid=FALSE) + 
    scale_y_discrete("", breaks=NA)

Answer 1

当您要求ggplot在交换x和y位置后将日期值视为离散变量时，会出现错误。当你删除它时它会消失：

p = ggplot(points, aes(x=A, y=Date)) +
     geom_point(aes(colour=factor(A)), size=1.8) + 
     scale_shape(solid=FALSE) 
p

或者你可以通过将离散轴调用应用到x轴来消除这些线：

 p = ggplot(points, aes(x=A, y=Date)) +
    geom_point(aes(colour=factor(A)), size=1.8) + 
    scale_shape(solid=FALSE) + 
    scale_x_discrete("", breaks=NULL)
 P

不幸的是，问题的标题似乎与问题的文本没有明确的联系，所以我不知道这是不是你要求的。

如何根据另一列对一列进行排序？
