=================
Pick event demo 2
=================
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.
.. note::
This example exercises the interactive capabilities of Matplotlib, and this
will not appear in the static documentation. Please run this code on your
machine to see the interactivity.
You can copy and paste individual parts, or download the entire example
using the link at the bottom of the page.
