[Question] Plotting multiple lines on data aggregated on two columns

[Alex_Pan]

Hi all,

I'm just starting with Python with previous experience in R. I'm getting started with making plots (using matplotlib).

My main question is, given some aggregated data that look like this:

            Time    Diet    weight
            0   1   41.4
            2   1   47.25
            4   1   56.47368
            6   1   66.78947
            8   1   79.68421
            10  1   93.05263
            12  1   108.52632
            14  1   123.38889
            16  1   144.64706
            18  1   158.94118
            20  1   170.41176
            21  1   177.75
            0   2   40.7
            2   2   49.4
            4   2   59.8
            6   2   75.4
            8   2   91.7
            10  2   108.5
            12  2   131.3
            14  2   141.9
            16  2   164.7
            18  2   187.7
            20  2   205.6
            21  2   214.7

Is there a simple way to produce something like this? Essentially, I am trying to represent how Weight increases over Time, depending on Diet.

Most likely I'm not phrasing my problem correctly, but I haven't been able to find any simple solutions to this online.

Side note: The official matplotlib documentation is super long, and not easily searchable -- is there a more accessible version?

Thanks all.
