DiscreteLocator

class DiscreteLocator(locs, **kwargs)

Bases: Locator

A tick locator suitable for discretized colorbars. Adds ticks to some subset of the location list depending on the available space determined from get_tick_space. Zero will be used if it appears in the location list, and step sizes along the location list are restricted to “nice” intervals by default.

Parameters

• locs (array-like) – The tick location list.

• nbins (int, optional) – Maximum number of ticks to select. By default this is automatically determined based on the the axis length and tick label font size.

• minor (bool, default: False) – Whether this is for “minor” ticks. Setting to True will select more ticks with an index step that divides the index step used for “major” ticks.

• steps (array-like of int, default: [1 2 3 4 5 6 8]) – Valid integer index steps when selecting from the tick list. Must fall between 1 and 9. Powers of 10 of these step sizes will also be permitted.

• vcenter (float, optional) – The optional non-zero center of the original diverging normalizer.

• min_n_ticks (int, default: 1) – The minimum number of ticks to select. See also nbins.

Methods Summary

__call__()	Return the locations of the ticks.
set_params([nbins, minor, steps, vcenter, ...])	Set the parameters for this locator.
tick_values(vmin, vmax)	Return the locations of the ticks.
