Plotting Multiple lines

I have a dataset where I want to plot some of the data as points and some as lines. Each dataset (points, lines) consists of subsets, which I want to plot individually.
I have the data in a dataframe. I can plot the points as I described, but, not the lines. I tried multi_line, but, I get an error

Reading the documentation it refers to xs, ys as lists of lists.

What is the best way to do this?

Can it be done from a dataframe?
Should I separate the data into two dataframes?

I have tried to search for an answer, but, with no success

thanks
