1.横坐标设置时间格式
import matplotlib.pyplot as plt
import matplotlib.dates as mdates
# 配置横坐标为日期格式
plt.gca().xaxis.set_major_formatter(mdates.DateFormatter('%Y/%m/%d'))
plt.gca().xaxis.set_major_locator(mdates.DayLocator())
例子:
from datetime import datetime
import matplotlib.dates as mdates
import matplotlib.pyplot as plt
# 生成横纵坐标信息
dates = ['01/02/1991', '01/03/1991', '01/04/1991']
xs = [datetime.strptime(d, '%m/%d/%Y').date() for d in dates]
ys = range(len(xs))
# 配置横坐标
plt.<a>本文来源gao($daima.com搞@代@#码(网</a>gca().xaxis.set_major_formatter(mdates.DateFormatter('%m/%d/%Y'))
plt.gca().xaxis.set_major_locator(mdates.DayLocator())
# Plot
plt.plot(xs, ys)
plt.gcf().autofmt_xdate() # 自动旋转日期标记
plt.show()
2.设置日期坐标轴主副刻度值
所有坐标轴日期格式类型
MinuteLocator: locate minutes（f）
HourLocator: locate hours
DayLocator: locate specified days of the month
WeekdayLocator: Locate days of the week, e.g., MO, TU
MonthLocator: locate months, e.g., 7 for july
YearLocator: locate years that are multiples of base
RRuleLocator: locate using a matplotlib.dates.rrulewrapper. The rrulewrapper is a simple wrapper around adateutil.rrule (dateutil) which allow almost arbitrary date tick specifications. See rrule example.
