Python x标签平均分布

Question

I am trying to get my labels turned up correctly. I want it to show 10 values on the list, but I have no idea how. The usual way to show it doesn't work and when there are a lot of values, it is hard to read, see the picture.

Here you see that it is impossible to read the data. Do you have an idea to make it work properly?

I have tried autoDateLocator, but that didn't work. The axis values were wrong. I also tried to do that manually, but the same result happened.

Thanks in advance!

I have kinda 'solved this issue'. I asked around and didn't really find an answer that suited my needs, as every tick always gets shown. However, when I keep the xtick_labels in the datetime-format, it gets sorted out by matplotlib itself, if there are too many values to show. This according to the dataset Armamatita provided

import matplotlib.pyplot as plt
import datetime

import numpy as np

x = np.array([datetime.datetime(i,1,1) for i in range(1700,2017)])
y = np.random.randint(0,100,len(x))
fig, ax = plt.subplots()
ax.plot(x,y)

plt.show()

I when the days I want to see is more than 14, I just let matplotlib pick te xtick_labels. When equal or less than 14, I add it myself using:

alldays = DayLocator() weekFormatter = DateFormatter('%a %b %d %Y')

and this right before returning the fig:

ax.xaxis.set_major_locator(alldays) ax.xaxis.set_major_formatter(weekFormatter)

It isn't the most neat pythonic code, but it does the trick.
