Locator

Locator(locator, *args, **kwargs)[source]

Returns a Locator instance, used to interpret the xlocator, xlocator_kw, ylocator, ylocator_kw, xminorlocator, xminorlocator_kw, yminorlocator, and yminorlocator_kw arguments when passed to format, and the locator, locator_kw minorlocator, and minorlocator_kw arguments when passed to colorbar methods wrapped by colorbar_wrapper.

Parameters

  • locator (Locator, str, float, or list of float) – If Locator, the object is returned.

    If number, specifies the multiple used to define tick separation. Returns a MultipleLocator instance.

    If list of numbers, these points are ticked. Returns a FixedLocator instance.

    If string, a dictionary lookup is performed (see below table).
