Bump chart can be used to display the change of grouped values.

Setup

• System Requirements: Cross-platform (Linux/MacOS/Windows)

• Programming language: R

• Dependent packages: ggplot2; ggbump; dplyr

# Install packages
if (!requireNamespace("ggplot2", quietly = TRUE)) {
  install.packages("ggplot2")
}
if (!requireNamespace("ggbump", quietly = TRUE)) {
  install.packages("ggbump")
}
if (!requireNamespace("dplyr", quietly = TRUE)) {
  install.packages("dplyr")
}

# Load packages
library(ggplot2)
library(ggbump)
library(dplyr)

Data Preparation

# Load data
data <- read.table("files/Hiplot/017-bumpchart-data.txt", header = T)

# View data
head(data)

     x y group
1 2019 4     A
2 2020 2     A
3 2021 2     A
4 2019 3     B
5 2020 1     B
6 2021 4     B

Visualization

# Bumpchart
p <- ggplot(data, aes(x = x, y = y, color = group)) +
  geom_bump(size = 1.5) +
  geom_point(size = 5) +
  geom_text(data = data %>% filter(x == min(x)),
            aes(x = x - 0.1, label = group),
            size = 5, hjust = 1) +
  geom_text(data = data %>% filter(x == max(x)),
            aes(x = x + 0.1, label = group),
            size = 5, hjust = 0) +
  theme_void() +
  theme(legend.position = "none") +
  scale_color_manual(values = c("#0571B0","#92C5DE","#F4A582","#CA0020"))
