class altair.DomainUnionWith(unionWith=Undefined, **kwds)

DomainUnionWith schema wrapper


unionWithanyOf(List(float), List(string), List(boolean), List(DateTime))

Customized domain values to be union with the field’s values.

  1. domain for quantitative fields can take one of the following forms:

  • a two-element array with minimum and maximum values. - an array with more than two entries, for Piecewise quantitative scales. (Alternatively, the domainMid property can be set for a diverging scale.) - a string value "unaggregated", if the input field is aggregated, to indicate that the domain should include the raw data values prior to the aggregation.

2) domain for temporal fields can be a two-element array minimum and maximum values, in the form of either timestamps or the DateTime definition objects.

3) domain for ordinal and nominal fields can be an array that lists valid input values.
