Additionally, you can use categorical types for the grouping variables to control the order of plot elements. Since we are dealing with a pandas data frame, you can create the boxplot using the pandas library directly. Helps us to identify the outliers easily.
First, what is a boxplot? How to make boxplots with pandas. There are a couple ways to graph a boxplot through python.
In this example, we are plotting the sepal_length, sepal_width, petal_length, and the petal_width of an. # boxplot with pandas df.plot.box(title='boxplot with pandas'); Boxplot (by = 'x') a list of strings (i.e.
Sns.boxplot(x='species', y=var, data=iris, ax=subplot) sns.swarmplot(x='species', y=var, data=iris, ax=subplot) fig.tight_layout() plt.show() Using example from [seaborn boxplot example][1]: Boxplots are good to show and compare variable distributions.
