I have some data that looks something like this:
df =
id period 15-nov 16-nov 17-nov 18-nov
------------------------------------------------------
vodka night 1 2 3 1
vodka day 0 1 2 0
vodka evening 1 2 2 0
rum night 1 2 3 3
rum day 1 2 2 0
rum evening 1 3 2 1
What I would like to do is to plot the values of the header dates, but grouped by id and period. So essentially this would become 6 line plots, with the x-axis given as the dates.
However, maybe I'm just tired, but this data set is weirdly put together imo, so my usual groupby
stuff doesn't work because only some of the headers are the x-axis values. I was thinking about transforming the date columns into one single column, and then adding the date headers as another column giving me 4 total columns - but more rows, and then use the groupby
function. But I can't think of any clever way to do this, accept maybe doing it kind of manually.
So is that the way for me to go, or am I missing an easy transformation trick ?

You could unpivot your dataframe using
CodePudding user response:
import seaborn as sns
sns.set()
df.set_index(['id','period']).T.plot(kind='line')
