Matplotlib X轴DateTime -将数据集中在一起

import matplotlib.pyplot as plt
import matplotlib.dates as mdates

fig, ax = plt.subplots()

dates = [datetime.datetime.strptime(date, "%Y-%m-%d") for date in dates_list]

ax.xaxis.set_major_locator(mdates.AutoDateLocator())
ax.xaxis.set_major_formatter(mdates.DateFormatter('%Y-%m-%d'))

ax.plot(dates, data)

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

# 日期数据
dates_list = ['2022-01-01', '2022-01-02', '2022-01-03', '2022-01-04', '2022-01-05']
# 数据集
data = [10, 15, 8, 12, 9]

# 创建图形对象和子图对象
fig, ax = plt.subplots()

# 将日期数据转换为Matplotlib可识别的格式
dates = [datetime.datetime.strptime(date, "%Y-%m-%d") for date in dates_list]

# 设置X轴的定位器和格式化器
ax.xaxis.set_major_locator(mdates.AutoDateLocator())
ax.xaxis.set_major_formatter(mdates.DateFormatter('%Y-%m-%d'))

# 绘制图表
ax.plot(dates, data)

# 显示图表
plt.show()
