A multi-panel plot for visualizing the annual peak timing and amplitude of salmonellosis in the US from 1996–2017. The top-left panel shows the peak timing of salmonellosis by year; the bottom-right panel shows the annual amplitude by year. The bottom-left panel shows their combination: a scatterplot between peak timing and amplitude. Marker colour intensity indicates more historic vs. more recent data, horizontal and vertical whiskers provide measures of uncertainty, and red lines indicate median peak timing and amplitude across 22 years.
