I'm working with this code using
However, I can see that the numbers on the right hand side x axis are clustered closer together than the numbers on the left hand side, and I would like to make these even.
I know it has to do with the line:
plt.subplots_adjust(wspace=0, top=0.85, bottom=0.1, left=0.2, right=0.8)
I know how to change this manually (i.e. just change the right and left parameters). But I could never be sure that I was being accurate, as I would just be manually changing these parameters until they looked even?
I'm wondering if someone could show me how make the axes evenly spaced automatically, without manually changing the left
and right
parameters?

A way to solve this problem is to use the set_xlim
function from Matplotlib and apply it to your subplots. The code then looks like this:
import matplotlib.pyplot as plt
import matplotlib as mpl
import pandas as pd
import seaborn as sns
sns.set()
