Python visualizations in power bi -Issues with the visuals

 Hello experts,

I am running in to an error of ordering the month in power b visuals in python scripting.

Here is the code i am referring.

Can anyone help me to find me the way of ordering this on the pbi visual?

import matplotlib.pyplot as plt 
ax = plt.gca() 
dataset.plot(kind='line', x='Month', y='cases', color='red',ax=ax)
dataset.plot(kind='line', x='Month', y='deaths', color='green', ax=ax)
plt.show() 

when look in to the green line, it also not categorized clearly. can you help me on this?

And when i selected date, why the chart behaves like this?

My expectation was a flowing line chart on the visual. I have selected the current monthe in the filter.  This shows the data from Aug 1 to Aug 20, 2021.
