Plotting erros

[gabrielp18]

When running "plot_bar", because the new versions of python dataframe.append doesn't work anymore and needs to be replaced for concat, i got the following error:
`---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)

Hi @gabrielp18,

I've just fixed the error, download version 4.4.1.
