Ridgeline plot

From HandWiki

A ridgeline plot (also known as a joyplot[note 1]) is a series of line plots of distributions that are combined by vertical stacking to allow the easy visualization of changes in distributions over space or time. The plots are often overlapped slightly to allow the changes to be more clearly contrasted. [1][2][3][4]

Notes

  1. The name Joyplot is derived from the use of a Ridgeline plot of a pulsar on the front of Joy Division's album Unknown Pleasures.
