我正在使用python 2,下面的代码仅使用了一些示例数据,我的实际数据长度可能有所不同,可能不是很细致。
import numpy as np
import datetime
import matplotlib
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
x_values = [datetime.datetime(2018, 11, 8, 11, 16),
datetime.datetime(2018, 11, 8, 11, 17),
datetime.datetime(2018, 11, 8, 11, 18),
datetime.datetime(2018, 11, 8, 11, 19),
datetime.datetime(2018, 11, 8, 11, 20),
datetime.datetime(2018, 11, 8, 11, 21),
datetime.datetime(2018, 11, 8, 11, 22),
datetime.datetime(2018, 11, 8, 11, 23),
datetime.datetime(2018, 11, 8, 11, 24),
datetime.datetime(2018, 11, 8, 11, 25),
datetime.datetime(2018, 11, 8, 11, 26),
datetime.datetime(2018, 11, 8, 11, 27),
datetime.datetime(2018, 11, 8, 11, 28),
datetime.datetime(2018, 11, 8, 11, 29),
datetime.datetime(2018, 11, 8, 11, 30),
datetime.datetime(2018, 11, 8, 11, 31)]
y_values = [1392.1017964071857,

rects1 = ax.bar(x_values, y_values)
fig.tight_layout()
plt.show()
我应该如何自动设置条的宽度?就这样,我得到以下信息:
如果我将宽度设置为0.0006,那么对于示例数据来说看起来不错:
从中我得出了matplotlib以天为单位测量x轴的信息(因为0.0007天几乎正好是1分钟,这与我的时间间隔匹配,而0.0006给出了条之间的间隔),但是如果我得到每小时或几秒钟或几周等等。确定有自动处理此选项的选项吗?
