我正在使用 ggplot 制作点图使用下面的代码和数据生成以下图表。
ggplot(data=holder, aes(x=Coef, y=CoefShort, colour=factor(Name))) + geom_point() + labs(x="Value", y="Coefficient") + scale_colour_discrete("Model")
它们是大量的过度绘制，我想在点之间创建一些垂直分隔。但它必须是系统的，即顺序总是红-绿-蓝。
geom_stack似乎只在 x 值相同时才有效，而在 y 值相同时无效。我尝试使用相反的轴(交换 x 和 y)，做一个 position_dodge()然后做一个 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()
任何想法如何使用
geom_point() 实现堆叠?谢谢。数据:

最佳答案
积分在 geom_point是零宽度，所以你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()
