您可以使用
DateFormatter：
fig = plt.figure()ax = fig.add_subplot(111)ax.plot(your_dates, your_data)# format your data to desired format. Here I chose YYYY-MM-DD but you can set it to whatever you want.import matplotlib.dates as mdatesax.xaxis.set_major_formatter(mdates.DateFormatter('%Y-%m-%d'))# rotate and align the tick labels so they look betterfig.autofmt_xdate()
