pandas.DataFrame.plot arguments 'xlabel' & 'ylabel' not working.
Hello everyone.

I was rehearsing some exercises with pandas.DataFrame.plot. I stumbled upon one (apparent) issue regarding '_xlabel_' and '_ylabel_' arguments. I followed instructions provided at [https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.plot.html](this site), as that is my current working Pandas version. If my understanding is correct, those arguments are to display some _str_ inserted by user, at _xlabel_ & _ylabel_ respectively, right? What the documentation says is the following:

- xlabel: Name to use for the xlabel on x-axis --> ERROR SHOWN: 'Line2D' object has no property 'xlabel'
- ylabel: Name to use for the ylabel on Y-axis --> ERROR SHOWN: 'Line2D' object has no property 'yabel'

Currently, I am using the following lines of code AFTER df.plot() has been used, to obtain the desired result; however I'd love to know if the previously mentioned behaviour is an actual issue, or some missunderstanding on the current documentation:

`plt.ylabel(ylabel=my_ylabel, fontsize=tz) 
plt.xlabel(xlabel=my_xlabel, fontsize=tz)`

Thank you in advance.
