Save file dataframe.hist () to file

Question

I am trying to create a dataframe histogram and save it as a file.

Here is my code:

ax=df.hist('ColumnName')
fig=ax.get_figure()
fig.savefig('pictureName.png', dpi=100, 
bbox_inches='tight')

The first line works fine; however, the second line returns an error: AttributeError: the object 'numpy.ndarray' does not have the attribute 'get_figure'.

Because this question shows that get_figure () applies to serial.hist (), I also tried using ax=df['ColumnName'].hist()one that successfully created the histogram, but led to the same error message when I tried to implement get_figure ().

As recommended in this other question , I usually skip get_figure () and fig.savefig (), instead I select plt.savefig, but I'm doing a few numbers. In my experience, plt.savefig () is not reliable in storing multiple shapes, instead storing the same pattern several times, even when I use fig.close () after each shape creation and save.

I really want to solve this problem as carefully as possible so that I can seamlessly transfer the solution to other applications, instead of using a different tape every time I have to make a schedule.

Thank you for your help!

Can you try the following code?

import pandas as pd
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
df.hist('ColumnName', ax=ax)
fig.savefig('example.png')
