Use ggplot2. notch If FALSE (default) make a standard box plot. . if the notches of two boxes do not overlap, this suggests that the medians You can simply turn showfliers = False in seaborn. This syntax tells ggplot that we want to create a boxplot from our data, and from the variable mappings that weve set with the aes function. I usually overlay geom_point() with a jitter over geom_boxplot() and then hide the outliers so those points do not appear twice (the jitter means you can see both). Based on suggestions by @Sven Hohenstein, @Roland and @lukeA I have solved the problem for displaying multiple boxplots in expanded form without outliers. mapping. A question that comes up is what exactly do the box plots represent? You should be using dplyr filter() to filter out observations that you dont want.
