egttools.plotting.indicators.AutoMinorLocator

class AutoMinorLocator(n=None)

Bases: Locator

Dynamically find minor tick positions based on the positions of major ticks. The scale must be linear with major ticks evenly spaced.

n is the number of subdivisions of the interval between major ticks; e.g., n=2 will place a single minor tick midway between major ticks.

If n is omitted or None, it will be set to 5 or 4.

Methods

create_dummy_axis
nonsingular	Adjust a range as needed to avoid singularities.
raise_if_exceeds	Log at WARNING level if locs is longer than Locator.MAXTICKS.
set_axis
set_bounds	[Deprecated]
set_data_interval	[Deprecated]
set_params	Do nothing, and raise a warning.
set_view_interval	[Deprecated]
tick_values	Return the values of the located ticks given vmin and vmax.
view_limits	Select a scale for the range from vmin to vmax.

__call__()

Return the locations of the ticks.

__init__(n=None)

n is the number of subdivisions of the interval between major ticks; e.g., n=2 will place a single minor tick midway between major ticks.

If n is omitted or None, it will be set to 5 or 4.

create_dummy_axis(**kwargs)

nonsingular(v0, v1)

Adjust a range as needed to avoid singularities.

This method gets called during autoscaling, with (v0, v1) set to the data limits on the axes if the axes contains any data, or (-inf, +inf) if not.

• If v0 == v1 (possibly up to some floating point slop), this method returns an expanded interval around this value.

• If (v0, v1) == (-inf, +inf), this method returns appropriate default view limits.

• Otherwise, (v0, v1) is returned without modification.

raise_if_exceeds(locs)

Log at WARNING level if locs is longer than Locator.MAXTICKS.

This is intended to be called immediately before returning locs from __call__ to inform users in case their Locator returns a huge number of ticks, causing Matplotlib to run out of memory.

The “strange” name of this method dates back to when it would raise an exception instead of emitting a log.

set_axis(axis)

set_bounds(vmin, vmax)

[Deprecated]

Notes

Deprecated since version 3.5: Use Axis.set_view_interval and Axis.set_data_interval instead.

set_data_interval(vmin, vmax)

[Deprecated]

Notes

Deprecated since version 3.5: Use Axis.set_data_interval instead.

set_params(**kwargs)

Do nothing, and raise a warning. Any locator class not supporting the set_params() function will call this.

set_view_interval(vmin, vmax)

[Deprecated]

Notes

Deprecated since version 3.5: Use Axis.set_view_interval instead.

tick_values(vmin, vmax)

Return the values of the located ticks given vmin and vmax.

Note

To get tick locations with the vmin and vmax values defined automatically for the associated axis simply call the Locator instance:

>>> print(type(loc))
<type 'Locator'>
>>> print(loc())
[1, 2, 3, 4]

view_limits(vmin, vmax)

Select a scale for the range from vmin to vmax.

Subclasses should override this method to change locator behaviour.
