I am trying to change my x axis time data format. Currently the x-axis shows 'month-day hour' and I just want it to report the hours, preferable not in military time.
Here is the graph for reference:

and the code for the graph:
import datetime
import matplotlib.dates as md
plt.style.use('default')
from scipy.ndimage.filters import gaussian_filter1d
fig = plt.figure(figsize=(15, 4))
x = df1['Time']
y = df1['BG']
plt.xlabel('Time (hours/minutes)', fontsize = 'large')
plt.ylabel('Blood Glucose (mg/dL)', fontsize = 'large')
plt.title('Personal Metabolic Map - Day 1', fontsize = 'large')
ysmoothed = gaussian_filter1d(y, sigma=2)
plt.plot(x, ysmoothed, linewidth = 2.0)
axes = plt.gca()
axes.set_ylim([70,200])
plt.grid(color = 'k', linestyle = '--', linewidth = 1.0)
plt.grid(b=True, which = 'minor', color = 'k', linestyle = ':')
axes.xaxis.set_minor_locator(md.MinuteLocator(interval=15))
fig.autofmt_xdate()
I have tried adding major locator to 60 minutes:
axes.xaxis.set_major_locator(md.MinuteLocator(interval=60))
But this is the result I get....

It's worth mentioning that the time data I am pulling from my dataframe ('Time') is in datetime64[ns].
Any help would be greatly appreciated as I am not really a programmer and have just started to try and learn python for data processing and visualization purposes.
Thank you!
I expected the x-axis to be 'HH', but the actual output is 'Year'.
