The Axes class has two attributes, fmt_xdata and fmt_ydata, which if
defined are callables that take the x and y coords as floats and
return the format string used to format that bit of text that goes
into the toolbar. The default is to use the xaxis and yaxis
Formatters. See examples/date_demo1.py for some example code.
