"""
==========================
The default tick formatter
==========================

By default, tick labels are formatted using a `.ScalarFormatter`, which can be
configured via `~.axes.Axes.ticklabel_format`.  This example illustrates some
possible configurations:

- Default.
- ``useMathText=True``: Fancy formatting of mathematical expressions.
- ``useOffset=False``: Do not use offset notation; see
  `.ScalarFormatter.set_useOffset`.
