class cartopy.mpl.ticker.LongitudeLocator(nbins=8, *, dms=False, **kwargs)[source]#

Bases: MaxNLocator

A locator for longitudes that works even at very small scale.

  • dms (bool) – Allow the locator to stop on minutes and seconds (False by default)

  • nbins (int or 'auto', default: 10) – Maximum number of intervals; one less than max number of ticks. If the string ‘auto’, the number of bins will be automatically determined based on the length of the axis.

  • steps (array-like, optional) – Sequence of acceptable tick multiples, starting with 1 and ending with 10. For example, if steps=[1, 2, 4, 5, 10], 20, 40, 60 or 0.4, 0.6, 0.8 would be possible sets of ticks because they are multiples of 2. 30, 60, 90 would not be generated because 3 does not appear in this example list of steps.

  • integer (bool, default: False) – If True, ticks will take only integer values, provided at least min_n_ticks integers are found within the view limits.

  • symmetric (bool, default: False) – If True, autoscaling will result in a range symmetric about zero.

  • prune ({'lower', 'upper', 'both', None}, default: None) – Remove the ‘lower’ tick, the ‘upper’ tick, or ticks on ‘both’ sides if they fall exactly on an axis’ edge (this typically occurs when axes.autolimit_mode is ‘round_numbers’). Removing such ticks is mostly useful for stacked or ganged plots, where the upper tick of an axes overlaps with the lower tick of the axes above it.

  • min_n_ticks (int, default: 2) – Relax nbins and integer constraints if necessary to obtain this minimum number of ticks.
