SimpleLogTickLocator

class PlasmaCalcs.plotting.plot_tools.plot_tricks.SimpleLogTickLocator(base=10)

Bases: LogLocator

simple LogLocator: puts base^N for every next power of base.

Includes all powers, doesn’t check if it is too dense to look nice.

Also doesn’t check if it’s too sparse to look nice.

base: log base. default 10.

Methods

`create_dummy_axis`(**kwargs)
`nonsingular`(vmin, vmax)	Adjust a range as needed to avoid singularities.
`raise_if_exceeds`(locs)	Log at WARNING level if locs is longer than `Locator.MAXTICKS`.
`set_axis`(axis)
`set_params`([base, subs, numdecs, numticks])	Set parameters within this locator.
`tick_values`(vmin, vmax)	return all ticks from floor(log(vmin)) to ceil(log(vmax))
`view_limits`(vmin, vmax)	Try to choose the view limits intelligently.

Attributes

nonsingular(vmin, vmax)

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_params(base=None, subs=None, numdecs=<deprecated parameter>, numticks=None): Set parameters within this locator.

tick_values(vmin, vmax): return all ticks from floor(log(vmin)) to ceil(log(vmax))

(tick min and tick max won’t show up on the plot unless between view lims.)
