Is Datetime in Matplotlib different from that of the Datetime used in Pandas or Python3? Does it need to be explicitly converted using Matplotlib functions such as date2num?



Background:



matplotlib.dates says it uses floating point from 0001-01-01 UTC.




Matplotlib represents dates using floating point numbers specifying
the number of days since 0001-01-01 UTC, plus 1. For example,
0001-01-01, 06:00 is 1.25, not 0.25. Values < 1, i.e. dates before
0001-01-01 UTC are not supported.




Python Data Visualization with Matplotlib says:




we need to convert the values to float numbers supported by Matplotlib.




from matplotlib.dates import date2num
import pandas as pd

# Convert Date column from string to Python datetime object,
# then to float number that is supported by Matplotlib.
stock_df["Datetime"] = date2num(pd.to_datetime(stock_df["Date"], format="%Y-%m-%d").tolist())
