==============
Custom Ticker1
==============

The new ticker code was designed to explicitly support user customized
ticking. The documentation of :mod:`matplotlib.ticker` details this
process.  That code defines a lot of preset tickers but was primarily
designed to be user extensible.

In this example a user defined function is used to format the ticks in
millions of dollars on the y axis.
