bqplot.scales.LinearScale

class bqplot.scales.LinearScale(**kwargs)[source]

A linear scale.

An affine mapping from a numerical domain to a numerical range.

min

float or None (default: None) – if not None, min is the minimal value of the domain

max

float or None (default: None) – if not None, max is the maximal value of the domain

rtype

string (class-level attribute) – This attribute should not be modifed. The range type of a linear scale is numerical.

dtype

type (class-level attribute) – the associated data type / domain type

precedence

int (class-level attribute, default_value=2) – attribute used to determine which scale takes precedence in cases when two or more scales have the same rtype and dtype. default_value is 2 because for the same range and domain types, LinearScale should take precedence.

stabilized

bool (default: False) – if set to False, the domain of the scale is tied to the data range if set to True, the domain of the scale is updated only when the data range is beyond certain thresholds, given by the attributes mid_range and min_range.

mid_range

float (default: 0.8) – Proportion of the range that is spanned initially. Used only if stabilized is True.

min_range

float (default: 0.6) – Minimum proportion of the range that should be spanned by the data. If the data span falls beneath that level, the scale is reset. min_range must be <= mid_range. Used only if stabilized is True.
