Violin Plot from Scientific Research

Swarm, violin and boxplots showing the distribution of RBL2 expression in the prefrontal cortex (transcripts per million (TPM), y axis). Each point represents the expression of RBL2 in 1 of 87 prenatal human cortices (BrainVar 44 ) split by genotype into 3 groups on the basis of zygosity for the Group 2 50% MAF SNPs. The P value represents the difference between the homozygous alternate ( N = 28) and homozygous reference ( N = 30) groups. The centre is the median expression value. The lower and upper bounds of the box correspond to the first and third quartiles (the 25th and 75th percentiles). The upper/lower whiskers extend from the upper/lower bound to the largest/smallest value no further than 1.5× the interquartile range. Data beyond the end of the whiskers are outlying points and are plotted individually. Bars at the bottom indicate pairs of haplotypes (derived from the data shown in c making up each genotype).
