[−][src]Struct vega_lite_4::SpecEncoding
A key-value mapping between encoding channels and definition of fields.
A shared key-value mapping between encoding channels and definition of fields in the underlying layers.
Fields
angle: Option<AngleClass>
Rotation angle of point and text marks.
color: Option<ColorClass>
Color of the marks – either fill or stroke color based on the filled
property of mark
definition. By default, color
represents fill color for "area"
, "bar"
, "tick"
,
"text"
, "trail"
, "circle"
, and "square"
/ stroke color for "line"
and
"point"
.
Default value: If undefined, the default color depends on mark
config's color
property.
Note: 1) For fine-grained control over both fill and stroke colors of the marks, please
use the fill
and stroke
channels. The fill
or stroke
encodings have higher
precedence than color
, thus may override the color
encoding if conflicting encodings
are specified. 2) See the scale documentation for more information about customizing
color scheme.
column: Option<RowColumnEncodingFieldDef>
A field definition for the horizontal facet of trellis plots.
description: Option<DescriptionClass>
A text description of this mark for ARIA accessibility (SVG output only). For SVG output
the "aria-label"
attribute will be set to this description.
detail: Option<Detail>
Additional levels of detail for grouping data in aggregate views and in line, trail, and area marks without mapping data to a specific visual channel.
facet: Option<FacetEncodingFieldDef>
A field definition for the (flexible) facet of trellis plots.
If either row
or column
is specified, this channel will be ignored.
fill: Option<FillClass>
Fill color of the marks. Default value: If undefined, the default color depends on
mark config's color
property.
Note: The fill
encoding has higher precedence than color
, thus may override the
color
encoding if conflicting encodings are specified.
fill_opacity: Option<FillOpacityClass>
Fill opacity of the marks.
Default value: If undefined, the default opacity depends on mark
config's fillOpacity
property.
href: Option<HrefClass>
A URL to load upon mouse click.
key: Option<KeyClass>
A data field to use as a unique key for data binding. When a visualization’s data is updated, the key value will be used to match data elements to existing mark instances. Use a key channel to enable object constancy for transitions over dynamic data.
latitude: Option<LatitudeClass>
Latitude position of geographically projected marks.
latitude2: Option<Latitude2Class>
Latitude-2 position for geographically projected ranged "area"
, "bar"
, "rect"
, and
"rule"
.
longitude: Option<LongitudeClass>
Longitude position of geographically projected marks.
longitude2: Option<Longitude2Class>
Longitude-2 position for geographically projected ranged "area"
, "bar"
, "rect"
,
and "rule"
.
opacity: Option<OpacityClass>
Opacity of the marks.
Default value: If undefined, the default opacity depends on mark
config's opacity
property.
order: Option<Order>
Order of the marks. - For stacked marks, this order
channel encodes stack
order. - For line and trail
marks, this order
channel encodes order of data points in the lines. This can be useful
for creating a connected
scatterplot.
Setting order
to {"value": null}
makes the line marks use the original order in the
data sources. - Otherwise, this order
channel encodes layer order of the marks.
Note: In aggregate plots, order
field should be aggregate
d to avoid creating
additional aggregation grouping.
radius: Option<RadiusClass>
The outer radius in pixels of arc marks.
radius2: Option<Radius2Class>
The inner radius in pixels of arc marks.
row: Option<RowColumnEncodingFieldDef>
A field definition for the vertical facet of trellis plots.
shape: Option<MarkPropDefStringNullTypeForShape>
Shape of the mark.
-
For
point
marks the supported values include: - plotting shapes:"circle"
,"square"
,"cross"
,"diamond"
,"triangle-up"
,"triangle-down"
,"triangle-right"
, or"triangle-left"
. - the line symbol"stroke"
- centered directional shapes"arrow"
,"wedge"
, or"triangle"
- a custom SVG path string (For correct sizing, custom shape paths should be defined within a square bounding box with coordinates ranging from -1 to 1 along both the x and y dimensions.) -
For
geoshape
marks it should be a field definition of the geojson data
Default value: If undefined, the default shape depends on mark
config's shape
property. ("circle"
if unset.)
size: Option<SizeClass>
Size of the mark. - For "point"
, "square"
and "circle"
, – the symbol size, or pixel
area of the mark. - For "bar"
and "tick"
– the bar and tick's size. - For "text"
–
the text's font size. - Size is unsupported for "line"
, "area"
, and "rect"
. (Use
"trail"
instead of line with varying size)
stroke: Option<StrokeClass>
Stroke color of the marks. Default value: If undefined, the default color depends on
mark config's color
property.
Note: The stroke
encoding has higher precedence than color
, thus may override the
color
encoding if conflicting encodings are specified.
stroke_dash: Option<MarkPropDefNumber>
Stroke dash of the marks.
Default value: [1,0]
(No dash).
stroke_opacity: Option<StrokeOpacityClass>
Stroke opacity of the marks.
Default value: If undefined, the default opacity depends on mark
config's strokeOpacity
property.
stroke_width: Option<StrokeWidthClass>
Stroke width of the marks.
Default value: If undefined, the default stroke width depends on mark
config's strokeWidth
property.
text: Option<TextDef>
Text of the text
mark.
theta: Option<ThetaClass>
-
For arc marks, the arc length in radians if theta2 is not specified, otherwise the start arc angle. (A value of 0 indicates up or “north”, increasing values proceed clockwise.)
-
For text marks, polar coordinate angle in radians.
theta2: Option<Theta2Class>
The end angle of arc marks in radians. A value of 0 indicates up or “north”, increasing values proceed clockwise.
tooltip: Option<EncodingTooltip>
The tooltip text to show upon mouse hover. Specifying tooltip
encoding overrides the
tooltip
property in the mark
definition.
See the tooltip
documentation for
a detailed discussion about tooltip in Vega-Lite.
url: Option<UrlClass>
The URL of an image mark.
x: Option<XClass>
X coordinates of the marks, or width of horizontal "bar"
and "area"
without specified
x2
or width
.
The value
of this channel can be a number or a string "width"
for the width of the
plot.
x2: Option<X2Class>
X2 coordinates for ranged "area"
, "bar"
, "rect"
, and "rule"
.
The value
of this channel can be a number or a string "width"
for the width of the
plot.
x_error: Option<XErrorClass>
Error value of x coordinates for error specified "errorbar"
and "errorband"
.
x_error2: Option<XError2Class>
Secondary error value of x coordinates for error specified "errorbar"
and "errorband"
.
y: Option<YClass>
Y coordinates of the marks, or height of vertical "bar"
and "area"
without specified
y2
or height
.
The value
of this channel can be a number or a string "height"
for the height of the
plot.
y2: Option<Y2Class>
Y2 coordinates for ranged "area"
, "bar"
, "rect"
, and "rule"
.
The value
of this channel can be a number or a string "height"
for the height of the
plot.
y_error: Option<YErrorClass>
Error value of y coordinates for error specified "errorbar"
and "errorband"
.
y_error2: Option<YError2Class>
Secondary error value of y coordinates for error specified "errorbar"
and "errorband"
.
