AutoFormatter

class AutoFormatter(zerotrim=None, tickrange=None, wraprange=None, prefix=None, suffix=None, negpos=None, **kwargs)[source]

Bases: ScalarFormatter

The default formatter used for proplot tick labels. Replaces ScalarFormatter.

Parameters
  • zerotrim (bool, default: rc['format.zerotrim']) – Whether to trim trailing decimal zeros.

  • tickrange (2-tuple of float, optional) – Range within which major tick marks are labeled. All ticks are labeled by default.

  • wraprange (2-tuple of float, optional) – Range outside of which tick values are wrapped. For example, (-180, 180) will format a value of 200 as -160.

  • prefix, suffix (str, optional) – Prefix and suffix for all tick strings. The suffix is added before the optional negpos suffix.

  • negpos (str, optional) – Length-2 string indicating the suffix for “negative” and “positive” numbers, meant to replace the minus sign.

Other Parameters

**kwargs – Passed to matplotlib.ticker.ScalarFormatter.

Note

matplotlib.ticker.ScalarFormatter determines the number of significant digits based on the axis limits, and therefore may truncate digits while formatting ticks on highly non-linear axis scales like LogScale. AutoFormatter corrects this behavior, making it suitable for arbitrary axis scales. We therefore use AutoFormatter with every axis scale by default.

Methods Summary

__call__(x[, pos])

Convert number to a string.

get_offset()

Get the offset but always use math text.
