Fig. 3: Frequency distributions of experimental TRs of the different contactclusters of each multi-species biofilm.
From: A formal analysis of Listeria monocytogenes cross-contamination dynamics in multi-species biofilms

The lines represent the probability density functions (PDF) of the best-fit distributions obtained for each case: gamma distribution (dashed line) for clusters 1 and 2 of F96 and log-normal distribution (solid line) for all others.
