Is there an appropriate way of drawing histogram from a binning and frequencies table?
import pandas as pd
freq=[3,14,21,12,6]
i=pd.interval_range(start=50,freq=10,end=100,closed='left')
df=pd.DataFrame(index=i,data=freq)
df.columns=['Freq']
df.index.name='Class'
df.columns.name='Column'
print(df)
#??hist(df)
