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)_apitickerunitsc@s<eZdZeddZeddZeddZeddZd S) StrCategoryConvertercCs|durtdt|ttj|td}t"t dd|D}Wdn1s^0Y|j r|rtj dddtj |t dS||tj|jjt gd |S) a Convert strings in *value* to floats using mapping information stored in the *unit* object.
