Index not iterable in Pandas 0.25.0

[MatsZ]

Code Sample, a copy-pastable example if possible

import pandas as pd
import matplotlib.pyplot as plt

# Get graphs in the notebook:
%matplotlib inline

pd.show_versions()

df = pd.DataFrame({'A': [1, 2, 3, 4, 15, 20, 99]})

data = df['A']

plt.plot(data, (data.index.values + 1) / len(data))
plt.show()

plt.plot(data, (data.index + 1) / len(data))
plt.show()

Problem description

In Pandas 0.23.4 the percentiles in CDF graphs can be expressed as (data.index + 1) / len(data), but in Pandas 0.25.0 this has to be changed to (data.index.values + 1) / len(data). No distaster but lots of work to change in many scripts.

Expected Output

[two nice CDF plots]

Output of pd.show_versions()

@MatsZ thanks for the report!

I assume this is the same as what was reported in matplotlib/matplotlib#14992 / #27775, which is fixed both on the pandas side as matplotlib side. So with the first bug fix release of either projects, this should be solved (pandas 0.25.1 is targetted to be released tomorrow).

[MatsZ]

Thanks a lot for the quick reply, and sorry that I missed that this is already in the bug list! I googled on what I thought were appropriate terms but apparently missed this. Thanks for fixing it as well! Excellent!

No worries.

The 0.25.1 release should be today.
