我正在使用ggplot
和下面的代码和数据制作一个点图,该图和数据将产生以下图形。
ggplot(data=holder, aes(x=Coef, y=CoefShort, colour=factor(Name))) + geom_point() + labs(x="Value", y="Coefficient") + scale_colour_discrete("Model")
它们是大量的重复绘图,我想在点之间创建一些垂直分隔。但是它必须是系统的,即顺序始终是红绿蓝。
geom_stack
仅在x值相同时才起作用,而在y值相同时才起作用。我尝试使用相反的轴(交换x和y),先做position_dodge()
然后做coord_flip()
。这仅适用于条形,如下所示。ggplot(data=holder, aes(y=Coef, x=CoefShort, fill=factor(Name))) + geom_bar(position="dodge", aes(ymax=Coef)) + labs(y="Value", x="Coefficient") + scale_fill_discrete("Model") + coord_flip()
有什么想法如何实现
geom_point()
的堆叠吗?谢谢。数据:

最佳答案
geom_point
中的点是零宽度,因此您需要设置闪避的宽度:
ggplot(data=holder, aes(y=Coef, x=CoefShort, colour=factor(Name))) +
geom_point(position=position_dodge(width = 0.8)) +
labs(y="Value", x="Coefficient", colour = "Model") +
coord_flip()
