---------------------------------------
Summary: Matplotlib error when trying to plot some dates
Key: ZEPPELIN-4096
URL: https://issues.apache.org/jira/browse/ZEPPELIN-4096
Project: Zeppelin
Issue Type: Bug
Components: pySpark
Affects Versions: 0.8.1
Reporter: Henri Chabert
Hello team,
I have a problem for one of my script in which I'd like to plot with matplotlib
a Dataframe with datetime on the x axis. I've tried even with a very simple
Dataframe and there is always an exception raised.
This is the script you can try runing:
{code:java}
import matplotlib
import numpy
import pandas as pd
new_df = pd.DataFrame(data={"date":[strToDateTime("2019-03-01"),
strToDateTime("2019-03-02"), strToDateTime("2019-03-03"),
strToDateTime("2019-03-04")], "metrics":[1, 2, 3, 4]})
new_df.plot(x="date")
{code}
And here is the error message :
{code:java}

and is an invalid Matplotlib date value. This often happens if you pass a
non-datetime value to an axis that has datetime units
{code}
I have tried to run this script directly on Python on the terminal as well as
on a Jupyter notebook and it worked, that is why I think it is an isue coming
directly from Zeppelin.
Thank you for you help :)
