Pandas bar plot with binned range

Question

Is there a way to create a bar plot from continuous data binned into predefined intervals? For example,

In[1]: df
Out[1]: 
0      0.729630
1      0.699620
2         


        

Answer 1

You may consider using matplotlib to plot the histogram. Unlike pandas' hist function, matplotlib.pyplot.hist accepts an array as input for the bins.

import numpy as np; np.random.seed(0)
import matplotlib.pyplot as plt
import pandas as pd

x = np.random.rand(120)
df = pd.DataFrame({"x":x})

bins= [0,0.35,0.7,1]
plt.hist(df.values, bins=bins, edgecolor="k")
plt.xticks(bins)

plt.show()
