I'm trying to join the points of a plot with at least 70 subplots, since it is not a scatter (because I can't use it since they are not series), I've tried marker = 'o-', but doesn't work. The data is in the format %mm-%yy, there are at least 6 different months (as a date column), and not for every column (Fund names) there exist any data in an specific month, however I want to join all the points from the same column even if they skipped any date.
I'm trying this, however it only joins the data that corresponds to following months.
df.plot(subplots = True, figsize = (20,20), layout = (14,5),legend=False,marker='o')
