[−][src]Struct vega_lite_3::LayerSpec
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.
Base interface for a unit (single-view) specification.
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<f64>
The height of a visualization.
Default value:
- If a view's
autosize
type is"fit"
or its y-channel has a continuous scale, the height will be the value ofconfig.view.height
. - For y-axis with a band or point scale: if
rangeStep
is a numeric value or unspecified, the height is determined by the range step, paddings, and the cardinality of the field mapped to y-channel. Otherwise, if therangeStep
isnull
, the height will be the value ofconfig.view.height
. - If no field is mapped to
y
channel, theheight
will be the value ofrangeStep
.
Note: For plots with row
and column
channels, this represents the
height of a single view.
See also: The documentation for width and height contains more examples.
layer: Option<Vec<LayerSpec>>
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<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<Resolve>
Scale, axis, and legend resolutions for view composition specifications.
title: Option<Title>
Title for the plot.
transform: Option<Vec<Transform>>
An array of data transformations such as filter and new field calculation.
view: Option<ViewBackground>
An object defining the view background's fill and stroke.
Default value: none (transparent)
width: Option<f64>
The width of a visualization.
Default value: This will be determined by the following rules:
- If a view's
autosize
type is"fit"
or its x-channel has a continuous scale, the width will be the value ofconfig.view.width
. - For x-axis with a band or point scale: if
rangeStep
is a numeric value or unspecified, the width is determined by the range step, paddings, and the cardinality of the field mapped to x-channel. Otherwise, if therangeStep
isnull
, the width will be the value ofconfig.view.width
. - If no field is mapped to
x
channel, thewidth
will be the value ofconfig.scale.textXRangeStep
fortext
mark and the value ofrangeStep
for other marks.
Note: For plots with row
and column
channels, this represents the
width of a single view.
See also: The documentation for width and height contains more examples.
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.
