pylab/matplotlib 日期标签控制

今天遇到了同样的问题，经过搜索，搜到下面这篇文章

Today I struggled a bit with
pylab's plot_date function and overlapping date tick labels:



After some googling, I found that pylab offers
nice flexible date tick control and formatting. I added a date tick locator and a date formatter to the mix as follows:

import pylab
import matplotlib
import matplotlib.dates

fig = pylab.figure()
ax = fig.gca()

# Plotting stuff here ...
ax.plot_date(dates, values, 'b.-')

# Set major x ticks on Mondays.
ax.xaxis.set_major_locator(
matplotlib.dates.WeekdayLocator(byweekday=matplotlib.dates.MO)
)
ax.xaxis.set_major_formatter(
matplotlib.dates.DateFormatter('%a %d\n%b %Y')
)

and now I have this plot
