# Pick Event Demo2ΒΆ

Compute the mean (mu) and standard deviation (sigma) of 100 data sets and plot mu vs. sigma. When you click on one of the (mu, sigma) points, plot the raw data from the dataset that generated this point.

import numpy as np
import matplotlib.pyplot as plt

X = np.random.rand(100, 1000)
xs = np.mean(X, axis=1)
ys = np.std(X, axis=1)

fig, ax = plt.subplots()
ax.set_title('click on point to plot time series')
line, = ax.plot(xs, ys, 'o', picker=5)  # 5 points tolerance

def onpick(event):

if event.artist != line:
return True

N = len(event.ind)
if not N:
return True

figi, axs = plt.subplots(N, squeeze=False)
for ax, dataind in zip(axs.flat, event.ind):
ax.plot(X[dataind])
ax.text(.05, .9, 'mu=%1.3f\nsigma=%1.3f' % (xs[dataind], ys[dataind]),
transform=ax.transAxes, va='top')
ax.set_ylim(-0.5, 1.5)
figi.show()
return True

fig.canvas.mpl_connect('pick_event', onpick)
