get_axes not present?

[Mahmood Naderan]

Hi
I am using the following versions


>>> import matplotlib
>>> print(matplotlib. __version__)
3.3.4
>>> import pandas as pd
>>> print(pd.__version__)
1.2.3
>>> import sys
>>> sys.version_info
sys.version_info(major=3, minor=8, micro=10, releaselevel='final', serial=0)



In my code, I use axes in Pandas plot() like this (note that I omit some variables in this snippet to highlight the problem):



def plot_dataframe(df, cnt, axes):
    plt.subplot(2, 1, 1)
    ax1 = row.plot( fontsize=font_size, linewidth=line_width, markersize=marker_size, marker='o', title='Raw values', label=cnt, ax=axes[0] )



def plot_kernels(my_dict2):
    fig,axes = plt.subplots(2,1, figsize=(20, 15))
    should_plot = plot_dataframe(df, cnt, axes=axes)
    for ax in axes:
        ax.legend()
    plt.show()



However, I get this error:


Traceback (most recent call last):
  File "process_csv.py", line 174, in <module>
    plot_kernels( my_dict2 )
  File "process_csv.py", line 62, in plot_kernels
    should_plot = plot_dataframe(df, cnt, axes=axes)
  File "process_csv.py", line 34, in plot_dataframe

    ax for ax in self.axes[0].get_figure().get_axes() if isinstance(ax, Subplot)
AttributeError: 'NoneType' object has no attribute 'get_axes'




I guess there is a mismatch between versions. Is there any workaround for that?
