ggjoy

Geoms to make joyplots using ggplot2, written by Claus O. Wilke

Note: This is early alpha software. As of today (July 13, 2017), the package is only 4 days old. While things generally work, you may encounter problems. Also, I make no guarantees at this time that the api is stable. For feedback and feature requests, please open issues on github.

About joyplots

Joyplots are partially overlapping line plots that create the impression of a mountain range. They can be quite useful for visualizing changes in distributions over time or space. The name "joyplot" was proposed by Jenny Bryan on Twitter on April 24, 2017, in reference to the iconic cover art for Joy Division's album Unknown Pleasures.
