I choose to use ggplot2 in R language, which is the splicing of box chart and heat map. The heat map on the right can be realized with the help of geom_point () function, changing the shape of the point into a square, the value mapping the color according to the positive and negative, and the size according to a certain value.

First construct a dataset set.seed ("20200407")

X =-1 & value

< -0.7 ~ -0.8, value >

=-0.7 & value

< -0.5 ~ -0.6, value >

=-0.5 & value

< -0.3 ~ -0.4, value >

=-0.3 & value 0 & value 0.3 & value 0.5 & value 0.7 & value df2

Construction data is used to add segment df3
