Hrishikesh S created ZEPPELIN-3223:
--------------------------------------
Summary: Plotting time series data raises ValueError alternate
times
Key: ZEPPELIN-3223
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3223
Project: Zeppelin
Issue Type: Bug
Components: pySpark, python-interpreter
Affects Versions: 0.7.3, 0.7.2
Reporter: Hrishikesh S
When a time series data of type datetime64 is plotted, it raises
*{{ValueError: ordinal}}* *{{must be >= 1}}* every alternate times.
Here's a sample code to produce this error:
{{import pandas as pd}}
{{import numpy as np}}
{{import matplotlib.pyplot as plt}}
{{rng = pd.date_range('1/1/2000', periods=10, freq='M')}}
{{ts = pd.Series(np.random.randn(len(rng)), index=rng)}}
{{# Plotting the data:}}
{{orig = plt.plot(ts)}}
{{plt.show()}}
Running this code for the first time results in the above mentioned
*{{ValueError}}*, but the plot appears when the same code is run again in the
same cell. But the error again returns in the third run, and thus, this error
appears every alternate time. Here is the traceback:
