Here is an example as far as I can understand what your goal is

import datetime as dt
import matplotlib.pyplot as plt
import matplotlib.dates as mdates
import random

x = mdates.drange(dt.datetime(2021, 3, 1, 0, 0, 0), dt.datetime(2021, 3, 3, 0, 0, 0),
                     dt.timedelta(hours=1))
y = [random.randint(0,100) for _ in range(len(x))]
time = mdates.drange(dt.datetime(2021, 3, 1, 0, 0, 0), dt.datetime(2021, 3, 3, 1, 0, 0),
                     dt.timedelta(hours=6))
 
fig, ax = plt.subplots(figsize=(8, 6))
plt.xticks(time)
ax.xaxis.set_major_formatter(mdates.DateFormatter("%m-%d %H:%M"))
# ax.xaxis.set_minor_formatter(mdates.DateFormatter("%m-%d %H:%M"))
ax.plot(x, y, 'bo-')
ax.set(title='Active Calls', ylabel='Calls', xlabel='Time')
ax.grid()
 
ax.xaxis_date() # Default date formatter
fig.autofmt_xdate()
 
plt.show()
