==============
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.

    def millions(x, pos):
        """The two args are the value and tick position."""
        return '${:1.1f}M'.format(x*1e-6)

    fig, ax = plt.subplots()
    # Use automatic FuncFormatter creation
    ax.yaxis.set_major_formatter(millions)
    ax.bar(['Bill', 'Fred', 'Mary', 'Sue'], money)
    plt.show()
