Should be fairly straightforward to write a converter. Just follow the example of DateConverter in matplotlib.dates :https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/dates.py: class DateConverter(units.ConversionInterface): """ Converter for datetime.date and datetime.datetime data, or for date/time data represented as it would be converted by :func:`date2num`. The 'unit' tag for such data is None or a tzinfo instance. """ @staticmethod def axisinfo(unit, axis): """ Return the :class:`~matplotlib.units.AxisInfo` for *unit*. *unit* is a tzinfo instance or None. The *axis* argument is required but not used. """ tz = unit majloc = AutoDateLocator(tz=tz) majfmt = AutoDateFormatter(majloc, tz=tz) datemin = datetime.date(2000, 1, 1) datemax = datetime.date(2010, 1, 1) return units.AxisInfo( majloc=majloc, majfmt=majfmt, label='', default_limits=(datemin, datemax)) @staticmethod def convert(value, unit, axis): """ If *value* is not already a number or sequence of numbers, convert it with :func:`date2num`. The *unit* and *axis* arguments are not used. """ if units.ConversionInterface.is_numlike(value): return value return date2num(value) @staticmethod def default_units(x, axis): 'Return the tzinfo instance of *x* or of its first element, or None' try: x = x[0] except (TypeError, IndexError): pass try: return x.tzinfo except AttributeError: pass return None units.registry[datetime.date] = DateConverter() units.registry[datetime.datetime] = DateConverter() ------------------------------------------------------------------------------ Special Offer -- Download ArcSight Logger for FREE!
