我用我的数据做了类似的事情,但是尽管透明度很高,但很难看到这些片段(我的数据的片段数比下面的例子少得多)才能看到它们的开头和结尾.

require(ggplot2)
ggplot(iris, aes(x = Petal.Length, xend = Petal.Width,
                 y = factor(Species), yend = factor(Species),
                 size = Sepal.Length)) +
    geom_segment(alpha = 0.05) + 
    geom_point(aes(shape = Species))

碰到这个解决方案,但线条交叉.有没有办法让抖动产生与尖端点的平行线？我试过position_dodge而不是position_jitter,但它需要ymax.可以ymax集成在一起使用geom_segment吗？

ggplot(iris, aes(x = Petal.Length, xend = Petal.Width,
                 y = factor(Species), yend = factor(Species))) +
    geom_segment(position = position_jitter(height = 0.25))+
    geom_point(aes(size = Sepal.Length, shape = Species))
