class
bqplot.scales.
Scale
(**kwargs)[source]¶ The base scale class.
Scale objects represent a mapping between data (the domain) and a visual quantity (The range).
-
scale_types
¶ A registry of existing scale types.
Type: dict (class-level attribute)
-
domain_class
¶ traitlet type used to validate values in of the domain of the scale.
Type: type (default: Float)
-
reverse
¶ whether the scale should be reversed.
Type: bool (default: False)
-
allow_padding
¶ indicates whether figures are allowed to add data padding to this scale or not.
Type: bool (default: True)
-
precedence
¶ attribute used to determine which scale takes precedence in cases when two or more scales have the same rtype and dtype.
Type: int (class-level attribute)
