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)
|
|||
|

|
|||

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:`date.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::

|
|
|
|||
|
|
.. 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.
|
|||
|
|

|||

|
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 </gallery/ticks/date_demo_rrule>`.
|
|||
|
|
|
|||
|
|
* `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
|
|||
|
|
---------------
|
|||
|
|
|
|||
|
|
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.

|

|
|
Set the epoch (origin for dates) for datetime calculations.
|
|||
|
|
|
|||
|
|
The default epoch is :rc:`date.epoch`.
|
|||
|
|
|
|||
|
|
If microsecond accuracy is desired, the date being plotted needs to be
|
|||
|
|
within approximately 70 years of the epoch. Matplotlib internally
|
|||
|
|
represents dates as days since the epoch, so floating point dynamic
|
|||
|
|
range needs to be within a factor of 2^52.
|
|||
|
|
|
|||
|
|
`~.dates.set_epoch` must be called before any dates are converted
|
|||
|
|
(i.e. near the import section) or a RuntimeError will be raised.
|
|||
|
|
|

|
|||
|
|
A `.Formatter` which attempts to figure out the best format to use for the
|
|||
|
|
date, and to make it as compact as possible, but still be complete. This is
|
|||
|
|
most useful when used with the `AutoDateLocator`::
|
|||
|
|
|
|||
|
|
>>> locator = AutoDateLocator()
|
|||
|
|
>>> formatter = ConciseDateFormatter(locator)
|
|||
|
|
|
|||
|
|
Parameters
|
|||
|
|
----------
|
|||
|
|
locator : `.ticker.Locator`
|
|||
|
|
Locator that this axis is using.
|
|||
|
|
|
|||
|
|
tz : str or `~datetime.tzinfo`, default: :rc:`timezone`
|
|||
|
|
Ticks timezone, passed to `.dates.num2date`.
|
|||
|
|
|
|||
|
|
formats : list of 6 strings, optional
|
|||
|
|
Format strings for 6 levels of tick labelling: mostly years,
|
|||
|
|
months, days, hours, minutes, and seconds. Strings use
|
|||
|
|
the same format codes as `~datetime.datetime.strftime`. Default is
|
|||
|
|
``['%Y', '%b', '%d', '%H:%M', '%H:%M', '%S.%f']``
|
|||
|
|
|
|||
|
|
zero_formats : list of 6 strings, optional
|
|||
|
|
Format strings for tick labels that are "zeros" for a given tick
|
|||
|
|
level. For instance, if most ticks are months, ticks around 1 Jan 2005
|
|||
|
|
will be labeled "Dec", "2005", "Feb". The default is
|
|||
|
|
``['', '%Y', '%b', '%b-%d', '%H:%M', '%H:%M']``
|
|||
|
|
|
|||
|
|
offset_formats : list of 6 strings, optional
|
|||
|
|
Format strings for the 6 levels that is applied to the "offset"
|
|||
|
|
string found on the right side of an x-axis, or top of a y-axis.
|
|||
|
|
Combined with the tick labels this should completely specify the
|
|||
|
|
date. The default is::
|
|||
|
|
|
|||
|
|
['', '%Y', '%Y-%b', '%Y-%b-%d', '%Y-%b-%d', '%Y-%b-%d %H:%M']
|
|||
|
|
|
|||
|
|
show_offset : bool, default: True
|
|||
|
|
Whether to show the offset or not.
|
|||
|
|
|
|||
|
|
usetex : bool, default: :rc:`text.usetex`
|
|||
|
|
To enable/disable the use of TeX's math mode for rendering the results
|
|||
|
|
of the formatter.

|

|
|
A `.Formatter` which attempts to figure out the best format to use. This
|
|||
|
|
is most useful when used with the `AutoDateLocator`.
|
|||
|
|
|
|||
|
|
`.AutoDateFormatter` has a ``.scale`` dictionary that maps tick scales (the
|
|||
|
|
interval in days between one major tick) to format strings; this dictionary
|
|||
|
|
defaults to ::
|
|||
|
|
|
|||
|
|
self.scaled = {
|
|||
|
|
DAYS_PER_YEAR: rcParams['date.autoformatter.year'],
|
|||
|
|
DAYS_PER_MONTH: rcParams['date.autoformatter.month'],
|
|||
|
|
1: rcParams['date.autoformatter.day'],
|
|||
|
|
1 / HOURS_PER_DAY: rcParams['date.autoformatter.hour'],
|
|||
|
|
1 / MINUTES_PER_DAY: rcParams['date.autoformatter.minute'],
|
|||
|
|
1 / SEC_PER_DAY: rcParams['date.autoformatter.second'],
|
|||
|
|
1 / MUSECONDS_PER_DAY: rcParams['date.autoformatter.microsecond'],
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
The formatter uses the format string corresponding to the lowest key in
|
|||
|
|
the dictionary that is greater or equal to the current scale. Dictionary
|
|||
|
|
entries can be customized::
|
|||
|
|
|
|||
|
|
locator = AutoDateLocator()
|
|||
|
|
formatter = AutoDateFormatter(locator)
|
|||
|
|
formatter.scaled[1/(24*60)] = '%M:%S' # only show min and sec
|
|||
|
|
|
|||
|
|
Custom callables can also be used instead of format strings. The following
|
|||
|
|
example shows how to use a custom format function to strip trailing zeros
|
|||
|
|
from decimal seconds and adds the date to the first ticklabel::
|
|||
|
|
|
|||
|
|
def my_format_function(x, pos=None):
|
|||
|
|
x = matplotlib.dates.num2date(x)
|
|||
|
|
if pos == 0:
|
|||
|
|
fmt = '%D %H:%M:%S.%f'
|
|||
|
|
else:
|
|||
|
|
fmt = '%H:%M:%S.%f'
|
|||
|
|
label = x.strftime(fmt)
|
|||
|
|
label = label.rstrip("0")
|
|||
|
|
label = label.rstrip(".")
|
|||
|
|
return label
|
|||
|
|
|
|||
|
|
formatter.scaled[1/(24*60)] = my_format_function

Parameters
|
|||
|
|
----------
|
|||
|
|
locator : `.ticker.Locator`
|
|||
|
|
Locator that this axis is using.
|
|||
|
|
|
|||
|
|
tz : str or `~datetime.tzinfo`, default: :rc:`timezone`
|
|||
|
|
Ticks timezone. If a string, *tz* is passed to `dateutil.tz`.
|
|||
|
|
|
|||
|
|
defaultfmt : str
|
|||
|
|
The default format to use if none of the values in ``self.scaled``
|
|||
|
|
are greater than the unit returned by ``locator._get_unit()``.
|
|||
|
|
|
|||
|
|
usetex : bool, default: :rc:`text.usetex`
|
|||
|
|
To enable/disable the use of TeX's math mode for rendering the
|
|||
|
|
results of the formatter. If any entries in ``self.scaled`` are set
|
|||
|
|
as functions, then it is up to the customized function to enable or
|
|||
|
|
disable TeX's math mode itself.

|
|
The default is ::
|
|||
|
|
|
|||
|
|
self.intervald = {
|
|||
|
|
YEARLY : [1, 2, 4, 5, 10, 20, 40, 50, 100, 200, 400, 500,
|
|||
|
|
1000, 2000, 4000, 5000, 10000],
|
|||
|
|
MONTHLY : [1, 2, 3, 4, 6],
|
|||
|
|
DAILY : [1, 2, 3, 7, 14, 21],
|
|||
|
|
HOURLY : [1, 2, 3, 4, 6, 12],
|
|||
|
|
MINUTELY: [1, 5, 10, 15, 30],
|
|||
|
|
SECONDLY: [1, 5, 10, 15, 30],
|
|||
|
|
MICROSECONDLY: [1, 2, 5, 10, 20, 50, 100, 200, 500,
|
|||
|
|
1000, 2000, 5000, 10000, 20000, 50000,
|
|||
|
|
100000, 200000, 500000, 1000000],
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
where the keys are defined in `dateutil.rrule`.
|
|||
|
|
|
|||
|
|
The interval is used to specify multiples that are appropriate for
|
|||
|
|
the frequency of ticking. For instance, every 7 days is sensible
|
|||
|
|
for daily ticks, but for minutes/seconds, 15 or 30 make sense.
|
|||
|
|
|
|||
|
|
When customizing, you should only modify the values for the existing
|
|||
|
|
keys. You should not add or delete entries.
|
|||
|
|
|
|||
|
|
Example for forcing ticks every 3 hours::
|
|||
|
|
|
|||
|
|
locator = AutoDateLocator()
|
|||
|
|
locator.intervald[HOURLY] = [3] # only show every 3 hours

Parameters
|
|||
|
|
----------
|
|||
|
|
tz : str or `~datetime.tzinfo`, default: :rc:`timezone`
|
|||
|
|
Ticks timezone. If a string, *tz* is passed to `dateutil.tz`.
|
|||
|
|
minticks : int
|
|||
|
|
The minimum number of ticks desired; controls whether ticks occur
|
|||
|
|
yearly, monthly, etc.
|
|||
|
|
maxticks : int
|
|||
|
|
The maximum number of ticks desired; controls the interval between
|
|||
|
|
ticks (ticking every other, every 3, etc.). For fine-grained
|
|||
|
|
control, this can be a dictionary mapping individual rrule
|
|||
|
|
frequency constants (YEARLY, MONTHLY, etc.) to their own maximum
|
|||
|
|
number of ticks. This can be used to keep the number of ticks
|
|||
|
|
appropriate to the format chosen in `AutoDateFormatter`. Any
|
|||
|
|
frequency not specified in this dictionary is given a default
|
|||
|
|
value.
|
|||
|
|
interval_multiples : bool, default: True
|
|||
|
|
Whether ticks should be chosen to be multiple of the interval,
|
|||
|
|
locking them to 'nicer' locations. For example, this will force
|
|||
|
|
the ticks to be at hours 0, 6, 12, 18 when hourly ticking is done
|
|||
|
|
at 6 hour intervals.
