result of code

how can create plot grouped like:

this should work grouped bar chart similar 1 linked in comment:

gb = df.groupby(['element','alarm tekst']) gb['alarm tekst'].count().unstack().plot(kind = 'bar')

original suggestion aggregated bar:

you should include agg() function count total values.

data.groupby('element').agg('count').plot(kind = 'bar')

if sec column summed term can utilize agg(numpy.sum) instead:

import numpy data.groupby('element').agg(numpy.sum).plot(kind = 'bar')
