我获得了几个月的数据,但在几个月之间缺失了.如果我将整个数据集绘制在一个绘图中(其间有很多空白空间),这看起来很奇怪.

我写了一个小例子脚本来展示它是如何工作的(基于：

Python/Matplotlib – Is there a way to make a discontinuous axis?)

问题：我无法让x轴使用相同的日期格式！ ax或ax2都是正确的,但从来都不是.

你有什么主意吗？

import numpy as np

import matplotlib as mpl

import matplotlib.pyplot as plt

import datetime

def getDates(startdate, enddate):

days = (enddate + datetime.timedelta(days=1) - startdate).days

dates = [ startdate + datetime.timedelta(days=x) for x in range(0,days) ]

return dates

dates1 = getDates(datetime.datetime(2013,1,1), datetime.datetime(2013,1,31))

dates2 = getDates(datetime.datetime(2013,3,1), datetime.datetime(2013,3,31))

dates = dates1+dates2

data = np.arange(len(dates))

Locator = mpl.dates.DayLocator(interval=5)

Formatter = mpl.dates.DateFormatter('%d-%m-%y')

fig,(ax,ax2) = plt.subplots(1,2,sharey=True)

fig.subplots_adjust(wspace=0.05)

fig.set_size_inches(10,3)

ax.plot(dates, data)

ax2.plot(dates, data)

ax.legend(loc=1)

ax.set_ylim( 0, 61 )

ax.set_xlim( datetime.datetime(2013,1,1), datetime.datetime(2013,1,31) )

ax2.set_xlim( datetime.datetime(2013,3,1), datetime.datetime(2013,3,31) )

labels = ax.get_xticklabels()

for label in labels: label.set_rotation(30)

labels = ax2.get_xticklabels()

for label in labels: label.set_rotation(30)

ax.spines['right'].set_visible(False)

ax2.spines['left'].set_visible(False)

ax.tick_params(right='off')

ax2.tick_params(left='off')

ax2.yaxis.tick_right()

ax.xaxis.set_major_locator(Locator)

ax.xaxis.set_major_formatter(Formatter)

ax2.xaxis.set_major_locator(Locator)

ax2.xaxis.set_major_formatter(Formatter)

plt.savefig("test.png", bbox_inches='tight')

结果：
