"""
Sharing axis limits and views
=============================

It's common to make two or more plots which share an axis, e.g., two subplots
with time as a common axis.  When you pan and zoom around on one, you want the
other to move around with you.  To facilitate this, matplotlib Axes support a
``sharex`` and ``sharey`` attribute.  When you create a `~.pyplot.subplot` or
`~.pyplot.axes`, you can pass in a keyword indicating what Axes you want to
share with.
