Plot_date not applying drawstyle='steps-post'

I tried the following code -
import matplotlib

import matplotlib.pyplot as plt

import datetime

customdate = datetime.datetime(2016, 1, 1, 13, 30)

y = [ 2,4,6,8,10,12,14,16,18,20 ]

x = [customdate + datetime.timedelta(hours=i) for i in range(len(y))]

_fig,_ax = plt.subplots()


_ax.plot_date(x,y, drawstyle=‘steps-post’)


and got the output as -


The step plot is not created, but when I change to
_ax.plot(x,y, drawstyle=‘steps-post’) instead plot_date
I get a step plot


Why is the drawstyle not applied to plot_date ?

Cause the default line is not visible for plot_date.

ok thanks.
I had not given the linestyle value, when I give it as linestyle=‘solid’ I get the desired results
