Box Plot from Scientific Research

Prevalence (a) and strength (b) of trophic, non-trophic and hybrid links. Diamonds represent averages over time within lakes; boxes lower and upper hinges (bounds) correspond to the first and third quantiles (the 25th and 75th percentiles) across all lakes; and black bars represent the median (50th percentile). The upper whisker (maximum) extends from the hinge to the largest value no further than 1.5 the distance between the first and third quartile. The lower whisker (minimum) extends from the hinge to the smallest value at most 1.5 the distance between the first and third quartile of the hinge; data beyond the end of the whiskers are outliers. P -values are shown above the brackets and were calculated using pairwise comparisons and a Wilcoxon test (non-parametric).
