[−][src]Struct vega_lite_3::SpecClass
A specification of the view that gets faceted.
A full layered plot specification, which may contains encoding
and projection
properties that will be applied to underlying unit (single-view) specifications.
Unit spec that can have a composite mark and row or column channels (shorthand for a facet spec).
A specification of the view that gets repeated.
Any specification in Vega-Lite.
Base interface for a facet specification.
Base interface for a repeat specification.
Base interface for a generalized concatenation specification.
Base interface for a vertical concatenation specification.
Base interface for a horizontal concatenation specification.
Fields
data: Option<Data>
An object describing the data source
description: Option<String>
Description of this mark for commenting purpose.
encoding: Option<Encoding>
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.
align: Option<AlignUnion>
The alignment to apply to grid rows and columns.
The supported string values are "all"
, "each"
, and "none"
.
- For
"none"
, a flow layout will be used, in which adjacent subviews are simply placed one after the other. - For
"each"
, subviews will be aligned into a clean grid structure, but each row or column may be of variable size. - For
"all"
, subviews will be aligned and each row or column will be sized identically based on the maximum observed size. String values for this property will be applied to both grid rows and columns.
Alternatively, an object value of the form {"row": string, "column": string}
can be
used to supply different alignments for rows and columns.
Default value: "all"
.
bounds: Option<BoundsEnum>
The bounds calculation method to use for determining the extent of a sub-plot. One of
full
(the default) or flush
.
- If set to
full
, the entire calculated bounds (including axes, title, and legend) will be used. - If set to
flush
, only the specified width and height values for the sub-view will be used. Theflush
setting can be useful when attempting to place sub-plots without axes or legends into a uniform grid structure.
Default value: "full"
center: Option<VegaliteCenter>
Boolean flag indicating if subviews should be centered relative to their respective rows or columns.
An object value of the form {"row": boolean, "column": boolean}
can be used to supply
different centering values for rows and columns.
Default value: false
Boolean flag indicating if subviews should be centered relative to their respective rows or columns.
Default value: false
columns: Option<f64>
The number of columns to include in the view composition layout.
Default value: undefined
-- An infinite number of columns (a single row) will be
assumed. This is equivalent to
hconcat
(for concat
) and to using the column
channel (for facet
and repeat
).
Note:
- This property is only for:
- the general (wrappable)
concat
operator (nothconcat
/vconcat
) - the
facet
andrepeat
operator with one field/repetition definition (without row/column nesting)
- Setting the
columns
to1
is equivalent tovconcat
(forconcat
) and to using therow
channel (forfacet
andrepeat
).
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.
spacing: Option<Spacing>
The spacing in pixels between sub-views of the composition operator.
An object of the form {"row": number, "column": number}
can be used to set
different spacing values for rows and columns.
Default value: Depends on "spacing"
property of the view composition
configuration (20
by
default)
The spacing in pixels between sub-views of the concat operator.
Default value: 10
facet: Option<Facet>
Definition for how to facet the data. One of:
spec: Option<Box<SpecClass>>
A specification of the view that gets faceted.
A specification of the view that gets repeated.
repeat: Option<RepeatUnion>
Definition for fields to be repeated. One of:
- An array of fields to be repeated. If
"repeat"
is an array, the field can be referred using{"repeat": "repeat"}
- An object that mapped
"row"
and/or"column"
to the listed of fields to be repeated along the particular orientations. The objects{"repeat": "row"}
and{"repeat": "column"}
can be used to refer to the repeated field respectively.
concat: Option<Vec<Spec>>
A list of views to be concatenated.
vconcat: Option<Vec<Spec>>
A list of views to be concatenated and put into a column.
hconcat: Option<Vec<Spec>>
A list of views to be concatenated and put into a row.
