"""
The new ticker code was designed to explicity support user customized
ticking. The documentation
http://matplotlib.sourceforge.net/matplotlib.ticker.html 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
