}

A specification of the view that gets repeated.

A full layered plot specification, which may contains encoding and projection properties that will be applied to underlying unit (single-view) specifications.

A unit specification, which can contain either primitive marks or composite marks.

Fields

data: RemovableValue<UrlData>

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.

description: Option<String>

Description of this mark for commenting purpose.

encoding: Option<LayerEncoding>

A shared key-value mapping between encoding channels and definition of fields in the underlying layers.

A key-value mapping between encoding channels and definition of fields.

height: Option<HeightUnion>

The height of a visualization.

• For a plot with a continuous y-field, height should be a number. - For a plot with either a discrete y-field or no y-field, height can be either a number indicating a fixed height or an object in the form of {step: number} defining the height per discrete step. (No y-field is equivalent to having one discrete step.) - To enable responsive sizing on height, it should be set to "container".

Default value: Based on config.view.continuousHeight for a plot with a continuous y-field and config.view.discreteHeight otherwise.

Note: For plots with row and column channels, this represents the height of a single view and the "container" option cannot be used.

See also: height documentation.

Deprecated: Please avoid using width in a unit spec that’s a part of a layer spec.

layer: Option<Vec<LayerElement>>

Layer or single view specifications to be layered.

Note: Specifications inside layer cannot use row and column channels as layering facet specifications is not allowed. Instead, use the facet operator and place a layer inside a facet.

name: Option<String>

Name of the visualization for later reference.

projection: Option<Box<Projection>>

An object defining properties of the geographic projection shared by underlying layers.

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.

resolve: Option<Box<Resolve>>

Scale, axis, and legend resolutions for view composition specifications.

title: Option<TitleUnion>

Title for the plot.

transform: Option<Vec<Transform>>

An array of data transformations such as filter and new field calculation.

view: Option<Box<ViewBackground>>

An object defining the view background’s fill and stroke.

Default value: none (transparent)

Deprecated: Please avoid using width in a unit spec that’s a part of a layer spec.

width: Option<HeightUnion>

The width of a visualization.

• For a plot with a continuous x-field, width should be a number. - For a plot with either a discrete x-field or no x-field, width can be either a number indicating a fixed width or an object in the form of {step: number} defining the width per discrete step. (No x-field is equivalent to having one discrete step.) - To enable responsive sizing on width, it should be set to "container".

Default value: Based on config.view.continuousWidth for a plot with a continuous x-field and config.view.discreteWidth otherwise.

Note: For plots with row and column channels, this represents the width of a single view and the "container" option cannot be used.

See also: width documentation.

Deprecated: Please avoid using width in a unit spec that’s a part of a layer spec.

mark: Option<AnyMark>

A string describing the mark type (one of "bar", "circle", "square", "tick", "line", "area", "point", "rule", "geoshape", and "text") or a mark definition object.

selection: Option<HashMap<String, SelectionDef>>

A key-value mapping between selection names and definitions.
