Locator

Locator(locator, *args, **kwargs)

Return a Locator instance. This function is 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).

  Key	Class	Description
  'null', 'none'	NullLocator	No ticks
  'auto'	AutoLocator	Major ticks at sensible locations
  'minor'	AutoMinorLocator	Minor ticks at sensible locations
  'date'	AutoDateLocator	Default tick locations for datetime axes
  'fixed'	FixedLocator	Ticks at these exact locations
  'index'	IndexLocator	Ticks on the non-negative integers
  'linear'	LinearLocator	Exactly N ticks encompassing the axis limits, spaced as numpy.linspace(lo, hi, N)
  'log'	LogLocator	Ticks for log-scale axes
  'logminor'	LogLocator preset	Ticks for log-scale axes on the 1st through 9th multiples of each power of the base
  'logit'	LogitLocator	Ticks for logit-scale axes
  'logitminor'	LogitLocator preset	Ticks for logit-scale axes with minor=True passed to LogitLocator
  'maxn'	MaxNLocator	No more than N ticks at sensible locations
  'multiple'	MultipleLocator	Ticks every N step away from zero
  'symlog'	SymmetricalLogLocator	Ticks for symmetrical log-scale axes
  'symlogminor'	SymmetricalLogLocator preset	Ticks for symmetrical log-scale axes on the 1st through 9th multiples of each power of the base
  'theta'	ThetaLocator	Like the base locator but default locations are every numpy.pi/8 radians
  'year'	YearLocator	Ticks every N years
  'month'	MonthLocator	Ticks every N months
  'weekday'	WeekdayLocator	Ticks every N weekdays

• *args, **kwargs – Passed to the Locator class.

Returns

Locator – A Locator instance.
