[FIXED] Pandas histogram with legend

Issue

My dataframe looks like this:

Customer ID	Age	Is True
123	31	1
124	33	1
125	45	0
126	27	0
127	37	1
128	39	0
129	49	0
130	30	0
131	30	0
132	38	1

I can create age histogram like this:

df.Age.hist()
plt.title('Age')
plt.xlabel('Age')
plt.ylabel('Frequency')

And I will get:

I would like to add a legend of the 'Is True' field. For each Bin, I would like to see what portion is 1. How can I do that?

Solution

I'm not sure you can do that with Matplotlib. But I know you can with Plotly.

import plotly.express as px
df = px.data.tips()
fig = px.histogram(df, x="total_bill", color="sex")
fig.show()
