平均值/标准差（也许是R？）的python图

Question

Hi I'm trying to produce a plot with the mean and standard deviation marked for a single realization of a random process as in the linked diagram. I've looked at python charting but can't find any packages that produce a similar plot.

Answer 1

import numpy as np
import matplotlib.pyplot as plt

xs = np.linspace(-np.pi, np.pi, 30)
ys = np.sin(xs)
plt.plot(xs, xs, ys, '-gD')
plt.title('Standard Deviation: %s; marker represents the average of the data (%s)' % (np.mean(ys), np.std(ys)))

Does that work for you?
