Matplotlib bar plot does not display string xticklabels

[JulianWgs]

When using a normal bar plot from matplotlib the string xticklabels are not converted, but instead the integer value.

import matplotlib.pyplot as plt

plt.bar(["A", "B"], [1, 2])
print(tikzplotlib.get_tikz_code())

\begin{axis}[

\draw[draw=none,fill=color0] (axis cs:0.6,0) rectangle (axis cs:1.4,2);
\end{axis}

\end{tikzpicture}

Workaround or correct code:

import pandas as pd
pd.Series([1, 2], ["A", "B"]).plot.bar()
print(tikzplotlib.get_tikz_code())

I can confirm this issue also for boxplots.
