Bug summary
In my custom matplotlib style sheet, I want to format the dates in such a way that includes a new line character, i.e., %b %d\n%H:%M. But matplotlib will not recognize the new line character and instead prints \n as text on my figure.
More details here: https://stackoverflow.com/questions/59144140/matplotlib-cutsom-style-sheet-format-dates-with-new-line-character?noredirect=1#comment104516325_59144140
Code for reproduction
In my my_style.mplstyle file, I have this formatting instruction for the dates (note the new line character):
date.autoformatter.hour : %b %d\n%H:%MWhen I load the style sheet and make a plot with dates on the x axis, it displays the \n as text rather than recognizing it as a new line character.
import matplotlib.pyplot as plt
plt.style.use('my_style')
import pandas as pd
from datetime import datetime
DATES = pd.date_range(datetime(2019, 1, 1), datetime(2019, 1, 2), 6)
plt.plot(DATES, range(len(DATES)))Actual outcome
# If applicable, paste the console output here
#
#
Expected outcome
I can get the desired outcome if I use the manual method to change the date formats directly in my code, but I would rather avoid repeating these lines of code in all my plotting scripts. That is why I want to use the style sheet to do this.
import matplotlib.dates as mdates
myFmt = mdates.DateFormatter('%b %d\n%H:%M')
plt.plot(DATES, range(len(DATES)))
plt.gca().xaxis.set_major_formatter(myFmt)
