healpy.projaxes.HpxCartesianAxes.plot_date¶

HpxCartesianAxes.plot_date(x, y, fmt='bo', tz=None, xdate=True, ydate=False, **kwargs)¶

Plot with data with dates.

Call signature:

plot_date(x, y, fmt='bo', tz=None, xdate=True,
          ydate=False, **kwargs)

Similar to the plot() command, except the x or y (or both) data is considered to be dates, and the axis is labeled accordingly.

x and/or y can be a sequence of dates represented as float days since 0001-01-01 UTC.

Keyword arguments:

fmt: string

The plot format string.

tz: [ None | timezone string | tzinfo instance]

The time zone to use in labeling dates. If None, defaults to rc value.

xdate: [ True | False ]

If True, the x-axis will be labeled with dates.

ydate: [ False | True ]

If True, the y-axis will be labeled with dates.

Note if you are using custom date tickers and formatters, it may be necessary to set the formatters/locators after the call to plot_date() since plot_date() will set the default tick locator to matplotlib.dates.AutoDateLocator (if the tick locator is not already set to a matplotlib.dates.DateLocator instance) and the default tick formatter to matplotlib.dates.AutoDateFormatter (if the tick formatter is not already set to a matplotlib.dates.DateFormatter instance).
