""" This type stub file was generated by pyright. """ from matplotlib import _api, ticker, units """ Matplotlib provides sophisticated date plotting capabilities, standing on the shoulders of python :mod:`datetime` and the add-on module dateutil_. By default, Matplotlib uses the units machinery described in `~matplotlib.units` to convert `datetime.datetime`, and `numpy.datetime64` objects when plotted on an x- or y-axis. The user does not need to do anything for dates to be formatted, but dates often have strict formatting needs, so this module provides many tick locators and formatters. A basic example using `numpy.datetime64` is:: import numpy as np times = np.arange(np.datetime64('2001-01-02'), np.datetime64('2002-02-03'), np.timedelta64(75, 'm')) y = np.random.randn(len(times)) fig, ax = plt.subplots() ax.plot(times, y) .. seealso:: - :doc:`/gallery/text_labels_and_annotations/date` - :doc:`/gallery/ticks/date_concise_formatter` - :doc:`/gallery/ticks/date_demo_convert` .. _date-format: Matplotlib date format ---------------------- Matplotlib represents dates using floating point numbers specifying the number of days since a default epoch of 1970-01-01 UTC; for example, 1970-01-01, 06:00 is the floating point number 0.25. The formatters and locators require the use of `datetime.datetime` objects, so only dates between year 0001 and 9999 can be represented. Microsecond precision is achievable for (approximately) 70 years on either side of the epoch, and 20 microseconds for the rest of the allowable range of dates (year 0001 to 9999). The epoch can be changed at import time via `.dates.set_epoch` or :rc:`dates.epoch` to other dates if necessary; see :doc:`/gallery/ticks/date_precision_and_epochs` for a discussion. .. note:: Before Matplotlib 3.3, the epoch was 0000-12-31 which lost modern microsecond precision and also made the default axis limit of 0 an invalid datetime. In 3.3 the epoch was changed as above. To convert old ordinal floats to the new epoch, users can do:: new_ordinal = old_ordinal + mdates.date2num(np.datetime64('0000-12-31')) There are a number of helper functions to convert between :mod:`datetime` objects and Matplotlib dates: .. currentmodule:: matplotlib.dates .. autosummary:: :nosignatures: datestr2num date2num num2date num2timedelta drange set_epoch get_epoch .. note:: Like Python's `datetime.datetime`, Matplotlib uses the Gregorian calendar for all conversions between dates and floating point numbers. This practice is not universal, and calendar differences can cause confusing differences between what Python and Matplotlib give as the number of days since 0001-01-01 and what other software and databases yield. For example, the US Naval Observatory uses a calendar that switches from Julian to Gregorian in October, 1582. Hence, using their calculator, the number of days between 0001-01-01 and 2006-04-01 is 732403, whereas using the Gregorian calendar via the datetime module we find:: In [1]: date(2006, 4, 1).toordinal() - date(1, 1, 1).toordinal() Out[1]: 732401 All the Matplotlib date converters, locators and formatters are timezone aware. If no explicit timezone is provided, :rc:`timezone` is assumed, provided as a string. If you want to use a different timezone, pass the *tz* keyword argument of `num2date` to any date tick locators or formatters you create. This can be either a `datetime.tzinfo` instance or a string with the timezone name that can be parsed by `~dateutil.tz.gettz`. A wide range of specific and general purpose date tick locators and formatters are provided in this module. See :mod:`matplotlib.ticker` for general information on tick locators and formatters. These are described below. The dateutil_ module provides additional code to handle date ticking, making it easy to place ticks on any kinds of dates. See examples below. .. _dateutil: https://dateutil.readthedocs.io .. _date-locators: Date tick locators ------------------ Most of the date tick locators can locate single or multiple ticks. For example:: # import constants for the days of the week from matplotlib.dates import MO, TU, WE, TH, FR, SA, SU # tick on Mondays every week loc = WeekdayLocator(byweekday=MO, tz=tz) # tick on Mondays and Saturdays loc = WeekdayLocator(byweekday=(MO, SA)) In addition, most of the constructors take an interval argument:: # tick on Mondays every second week loc = WeekdayLocator(byweekday=MO, interval=2) The rrule locator allows completely general date ticking:: # tick every 5th easter rule = rrulewrapper(YEARLY, byeaster=1, interval=5) loc = RRuleLocator(rule) The available date tick locators are: * `MicrosecondLocator`: Locate microseconds. * `SecondLocator`: Locate seconds. * `MinuteLocator`: Locate minutes. * `HourLocator`: Locate hours. * `DayLocator`: Locate specified days of the month. * `WeekdayLocator`: Locate days of the week, e.g., MO, TU. * `MonthLocator`: Locate months, e.g., 7 for July. * `YearLocator`: Locate years that are multiples of base. * `RRuleLocator`: Locate using a `rrulewrapper`. `rrulewrapper` is a simple wrapper around dateutil_'s `dateutil.rrule` which allow almost arbitrary date tick specifications. See :doc:`rrule example `. * `AutoDateLocator`: On autoscale, this class picks the best `DateLocator` (e.g., `RRuleLocator`) to set the view limits and the tick locations. If called with ``interval_multiples=True`` it will make ticks line up with sensible multiples of the tick intervals. For example, if the interval is 4 hours, it will pick hours 0, 4, 8, etc. as ticks. This behaviour is not guaranteed by default. .. _date-formatters: Date formatters --------------- The available date formatters are: * `AutoDateFormatter`: attempts to figure out the best format to use. This is most useful when used with the `AutoDateLocator`. * `ConciseDateFormatter`: also attempts to figure out the best format to use, and to make the format as compact as possible while still having complete date information. This is most useful when used with the `AutoDateLocator`. * `DateFormatter`: use `~datetime.datetime.strftime` format strings.
