Pyramid plot

As explained in Statistics Slam Dunk

A pyramid plot is a visualization that uses mirrored or stacked horizontal bars to compare distributions across ordered categories.

How Statistics Slam Dunk covers it

How deep it goes

Explains sign conversion, reshaping, axis labeling, and ggplot2 construction, stopping short of statistical modeling.

Examples

Uses NBA seasons, real dollars, adjusted dollars, mirrored bars, and million-dollar axis labels.

What it assumes

Assumes basic R data frames and plotting while demonstrating data reshaping and negative-value encoding.

What you can do after

Build it from scratch in R by transforming paired measures and plotting them with ggplot2.

How it connects

Connects hierarchical data, stacked bar charts, data wrangling, pivot_longer(), and ggplot2.
