Closed. This question needs
I want to plot the dates with as months with which industries occurred the most during this months
How can I do that?
CodePudding user response：
So your problem seems to be that you have two different data types which makes creating a graph difficult. However you can reformat the data to the proper types you want which will make creating a graph in the way you intend much easier. Something like this should work for what your wanting.
import pandas as pd
import matplotlib.pyplot as plt
data = pd.DataFrame(
[{'date_raised':pd.to_datetime('2016-01-01 00:00:00'),'primary_industry':'Real Estate'},
{'date_raised':pd.to_datetime('2016-01-10 04:00:00'),'primary_industry':'IT Solutions'},
{'date_raised':pd.to_datetime('2016-01-04 04:00:00'),'primary_industry':'Multimedia'},
{'date_raised':pd.to_datetime('2016-01-05 04:00:00'),'primary_industry':'Technology'},
{'date_raised':pd.to_datetime('2016-01-09 04:00:00'),'primary_industry':'Technology'}]
)
result = data.sort_values('date_raised').groupby([data['date_raised'].dt.strftime('%B')])['primary_industry'].value_counts().unstack(level=1)
result.index.name = None
result.columns.names = [None]
ax = result.plot(kind='bar',use_index=True,rot=1)
ax.set_xlabel('Month')
ax.set_ylabel('Total Occurrences')
plt.show()
