How to plot histogram groups of dataframe?

Question

I have a dataframe of bins of page views in a specific site and the quantity of users in each bin a their share of users. It looks like that:

index	0-100	100-200	200-300
usersquantity	100	100	300
usershare	20	20	60

I am trying to plot a histogram of user quantity:

plt.hist(df.iloc[0], bins=[0,100,200,300])

But I get this error:

cannot determine next label for type <class 'str'>

I assume that this is because the index is categorical.

How can I fix this?

thanks a lot

Issue here is that, you are trying to use userquantity as a column. If you want to print histogram for userquantity row, then you can do this. See further comments inline

#Delete the index column as it is text.
df_new = df.drop('index', axis=1)
#Use iloc to get the values from row 'userquantity'
plt.hist(df_new.iloc[0], bins=[0,100,200,300])
plt.show()
