See :doc:`/gallery/lines_bars_and_markers/categorical_variables` for an example. The module uses Matplotlib's `matplotlib.units` mechanism to convert from strings to integers and provides a tick locator, a tick formatter, and the `.UnitData` class that creates and stores the string-to-integer mapping. ) OrderedDictN)_apicbooktickerunitsc@s<eZdZeddZeddZeddZeddZd S) StrCategoryConvertercCsf|durtdt|ttj|td}||tj|j j t gd|}t |s/|S|dS)a Convert strings in *value* to floats using mapping information stored in the *unit* object.
