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     ax1 = row.plot( fontsize=font_size, linewidth=line_width, markersize=marker_size, marker='o', title='Raw values', label=cnt, ax=axes[0] )   File "/home/mahmood/.local/lib/python3.8/site-packages/pandas/plotting/_core.py", line 955, in __call__     return plot_backend.plot(data, kind=kind, **kwargs)   File "/home/mahmood/.local/lib/python3.8/site-packages/pandas/plotting/_matplotlib/__init__.py", line 61, in plot     plot_obj.generate()   File "/home/mahmood/.local/lib/python3.8/site-packages/pandas/plotting/_matplotlib/core.py", line 283, in generate     self._adorn_subplots()   File "/home/mahmood/.local/lib/python3.8/site-packages/pandas/plotting/_matplotlib/core.py", line 483, in _adorn_subplots     all_axes = self._get_subplots()   File "/home/mahmood/.local/lib/python3.8/site-packages/pandas/plotting/_matplotlib/core.py", line 903, in _get_subplots     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? Regards, Mahmood
