Methods

__init__(*, intervals[, unison, unicode, ...])
create_dummy_axis(**kwargs)
fix_minus(s)	Some classes may want to replace a hyphen for minus with the proper Unicode symbol (U+2212) for typographical correctness. This is a helper method to perform such a replacement when it is enabled via :rc:`axes.unicode_minus`.
format_data(value)	Return the full string representation of the value with the position unspecified.
format_data_short(value)	Return a short string version of the tick value.
format_ticks(values)	Return the tick labels for all the ticks at once.
