matplotlib.axes.Axes.plot_date¶
-
Axes.
plot_date
(x, y, fmt='o', tz=None, xdate=True, ydate=False, *, data=None, **kwargs)[source]¶ Plot data that contains dates.
Similar to
plot
, this plots y vs. x as lines or markers. However, the axis labels are formatted as dates depending on xdate and ydate.Parameters: - x, yarray-like
The coordinates of the data points. If xdate or ydate is True, the respective values x or y are interpreted as Matplotlib dates.
- fmtstr, optional
The plot format string. For details, see the corresponding parameter in
plot
.- tztimezone string or
datetime.tzinfo
, default:rcParams["timezone"]
(default:'UTC'
) The time zone to use in labeling dates.
- xdatebool, default: True
If True, the x-axis will be interpreted as Matplotlib dates.
- ydatebool, default: False
If True, the y-axis will be interpreted as Matplotlib dates.
Returns: - lines
A list of
Line2D
objects representing the plotted data.
Other Parameters: - **kwargs
Keyword arguments control the

Notes
If you are using custom date tickers and formatters, it may be necessary to set the formatters/locators after the call to
plot_date
.plot_date
will set the default tick locator toAutoDateLocator
(if the tick locator is not already set to aDateLocator
instance) and the default tick formatter toAutoDateFormatter
(if the tick formatter is not already set to aDateFormatter
instance).Note
In addition to the above described arguments, this function can take a data keyword argument. If such a data argument is given, the following arguments can also be string
s
, which is interpreted asdata[s]
(unless this raises an exception): x, y.Objects passed as data must support item access (
data[s]
) and membership test (s in data
).
