Violin Plot from Scientific Research

In each violin graph, the x-axis indicates the bacterial strain; and the y-axis indicates the raw signal intensity of detected metabolites. The width of the violin plot is proportional to the estimated density of the observed data. The bottom and top of the box show the 25th and 75th percentile; and the horizontal line in the box indicates the median value. Statistical difference was evaluated by t-test (two-sided). The P values less than 0.05 are labeled, and all exact P values are provided in the data source file.
