How did monthly sea temperature in the Niño 3.4 region change from 2014 to 2017 (°C anomaly vs. 1991–2020)?
This is a real historical chart. Extraplot shows you the beginning and asks you to draw what happens next, then reveals the actual line. Below is the full series with the reveal point marked.
Solid line = visible part you would draw from · dashed violet = the actual revealed data after the cutoff.
