class altair.UnitSpec(mark=Undefined, data=Undefined, description=Undefined, encoding=Undefined, name=Undefined, params=Undefined, projection=Undefined, title=Undefined, transform=Undefined, **kwds)#

UnitSpec schema wrapper

Mapping(required=[mark]) Base interface for a unit (single-view) specification.

Attributes

markAnyMark: A string describing the mark type (one of "bar", "circle", "square", "tick", "line", "area", "point", "rule", "geoshape", and "text" ) or a mark definition object.
dataanyOf(Data, None): An object describing the data source. Set to null to ignore the parent’s data source. If no data is set, it is derived from the parent.
descriptionstring: Description of this mark for commenting purpose.
encodingEncoding: A key-value mapping between encoding channels and definition of fields.
namestring: Name of the visualization for later reference.
paramsList(anyOf(VariableParameter, SelectionParameter)): An array of parameters that may either be simple variables, or more complex selections that map user input to data queries.
projectionProjection: An object defining properties of geographic projection, which will be applied to shape path for "geoshape" marks and to latitude and "longitude" channels for other marks.
titleanyOf(Text, TitleParams): Title for the plot.
transformList(Transform): An array of data transformations such as filter and new field calculation.
