iPython/Jupyter Notebook and Pandas, how to plot multiple graphs in a for loop?

In the IPython notebook the best way to do this is often with subplots. You create multiple axes on the same figure and then render the figure in the notebook. For example:

import pandas as pd
import matplotlib.pyplot as plt

%matplotlib inline

ys = [[0,1,2,3,4],[4,3,2,1,0]]
x_ax = [0,1,2,3,4]

fig, axs = plt.subplots(ncols=2, figsize=(10, 4))
for i, y_ax in enumerate(ys):
    pd.Series(y_ax, index=x_ax).plot(kind='bar', ax=axs[i])
    axs[i].set_title('Plot number {}'.format(i+1))

generates the following charts

Just add the call to plt.show() after you plot the graph (you might want to import matplotlib.pyplot to do that), like this:

from pandas import Series
import matplotlib.pyplot as plt
%matplotlib inline

ys = [[0,1,2,3,4],[4,3,2,1,0]]
x_ax = [0,1,2,3,4]

for y_ax in ys:
    ts = Series(y_ax,index=x_ax)
    ts.plot(kind='bar', figsize=(15,5))
    plt.show()
