Displaying Changes Between Two Points Using Dumbbell Plots.

dumbbell R Package: Some More Examples

Step 1

Load libraries

suppressPackageStartupMessages({
library(tidyverse)
library(ggplot2) 
library(rlang)
library(utils)
library(data.table)
library(dumbbell)

     
})

Step 2

Get some data: Example data taken from https://plotly.com/r/dumbbell-plots/

s <- read.csv("https://raw.githubusercontent.com/plotly/datasets/master/school_earnings.csv")
s$School <- factor(s$School, levels = s$School[order(s$Men)])
s1<-s %>% mutate("type" = 'Gender earnings disparity') 

Step 3

Plot

dumbbell::dumbbell(xdf=s1,id="School",key = "type", column1 = "Women", column2 = "Men", delt=1 ,arrow = 1, lab1 = "Women", lab2="Men", p_col1 = "red", p_col2 = "blue" ,pt_val = 1 , pval = 2, textsize = 3) + 
xlim(60,170) + 
facet_wrap( . ~ type)
