 Good morning,

I'm looking for examples of creating a bar chart and then adding
a line chart on top of it (with the same y-axis). I haven't had
much luck with Google (probably using the wrong search terms).




You should be able to just call the bar() function and then call the plot() function using the same axes object.  For example (untested):

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.gca()

xs = np.arange(10)
ys = np.random.rand(10)

ax.bar(xs, ys)
ax.plot(xs, ys)


I hope that helps!
