English: Example of violin plot from the paper by Mohammadi et al. in PLoS Pathogens (doi:10.1371/journal.ppat.1003161). The legend of the figure reads: (B) Activity profile of individual steps of the viral life cycle estimated from the progression model. Each violin spans the 98% quantile of the viral step with width proportional to activity level at each given point in time. The plus symbol (‘+’) denotes the peak of the activity and the inner white violin its 95% bootstrap confidence interval. In the shaded area, expected values extrapolated beyond the last observed time point (24 h, dashed line) are shown.
