How to fix 'AttributeError: Unknown property figsize'?

I am trying to plot multiple graphs into 1 using a for loop and I encountered this problem. I tried it for the other loops and it works just fine but I don't know what happened with this one.

The files used are the exchange rates of EUR to USD for the past 2 years and I am trying to plot the date and the price on the graph. If I don't use figsize the graph is too small but it works.

import pandas as pd
import matplotlib.pyplot as plt

file = ['somefile.csv', 'otherfile.csv', 'anotherfile.csv']

for files in file:

    files1 = pd.read_csv ('%s' %files)

    files1.plot (kind='line', x='Date', y='Price', ax=ax, figsize=(15,10))

plt.legend()
plt.show()

One way around is using

plt.gcf().set_size_inches(15, 8)

So your code should be

import pandas as pd
import matplotlib.pyplot as plt

file = ['somefile.csv', 'otherfile.csv', 'anotherfile.csv']

for files in file:

    files1 = pd.read_csv ('%s' %files)

    files1.plot (kind='line', x='Date', y='Price', ax=ax)
plt.gcf().set_size_inches(15, 8))

plt.legend()
plt.show()

Since you want to specify axis as ax(ax=ax), best answer would be @Sheldore's. But there's actually an easier, also the most basic, way to this:

plt.figure(figsize=(15,10))

Put this before the for loop.

Use the following: Create first the axis object specifying the figure size and then use that object while plotting

fig, ax = plt.subplots(figsize=(15,10))

for files in file:
    files1 = pd.read_csv ('%s' %files)
    files1.plot (kind='line', x='Date', y='Price', ax=ax)
