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. If either fill or stroke channel is specified, color channel will be ignored.
2. See the scale documentation for more information about customizing color scheme.

Fill color of the marks. Default value: If undefined, the default color depends on mark config’s color property.

Note: When using fill channel, color channel will be ignored. To customize both fill and stroke, please use fill and stroke channels (not fill and color).

Opacity of the marks – either can be a value or a range.

Default value: If undefined, the default opacity depends on mark config’s opacity property.

For point marks the supported values are "circle" (default), "square", "cross", "diamond", "triangle-up", or "triangle-down", or else a custom SVG path string. 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.

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 color of the marks. Default value: If undefined, the default color depends on mark config’s color property.

Note: When using stroke channel, color channel will be ignored. To customize both stroke and fill, please use stroke and fill channels (not stroke and color).

A FieldDef with Condition { condition: {value: …}, field: …, … }

A ValueDef with Condition<ValueDef | FieldDef> { condition: {field: …} | {value: …}, value: …, }

Fields

aggregate: Option<AggregateOp>

Aggregation function for the field (e.g., mean, sum, median, min, max, count).

Default value: undefined (None)

bin: Option<Bin>

A flag for binning a quantitative field, or an object defining binning parameters. If true, default binning parameters will be applied.

Default value: false

condition: Option<ColorCondition>

One or more value definition(s) with a selection predicate.

Note: A field definition’s condition property can only contain value definitions since Vega-Lite only allows at most one encoded field per encoding channel.

A field definition or one or more value definition(s) with a selection predicate.

field: Option<Field>

Required. A string defining the name of the field from which to pull a data value or an object defining iterated values from the repeat operator.

Note: Dots (.) and brackets ([ and ]) can be used to access nested objects (e.g., "field": "foo.bar" and "field": "foo['bar']"). If field names contain dots or brackets but are not nested, you can use \\ to escape dots and brackets (e.g., "a\\.b" and "a\\[0\\]"). See more details about escaping in the field documentation.

Note: field is not required if aggregate is count.

legend: Option<Legend>

An object defining properties of the legend. If null, the legend for the encoding channel will be removed.

Default value: If undefined, default legend properties are applied.

scale: Option<Scale>

An object defining properties of the channel’s scale, which is the function that transforms values in the data domain (numbers, dates, strings, etc) to visual values (pixels, colors, sizes) of the encoding channels.

If null, the scale will be disabled and the data value will be directly encoded.

Default value: If undefined, default scale properties are applied.

sort: Option<Sort>

Sort order for the encoded field.

For continuous fields (quantitative or temporal), sort can be either "ascending" or "descending".

For discrete fields, sort can be one of the following:

• "ascending" or "descending" – for sorting by the values’ natural order in Javascript.
• A sort field definition for sorting by another field.
• An array specifying the field values in preferred order. In this case, the sort order will obey the values in the array, followed by any unspecified values in their original order. For discrete time field, values in the sort array can be date-time definition objects. In addition, for time units "month" and "day", the values can be the month or day names (case insensitive) or their 3-letter initials (e.g., "Mon", "Tue").
• null indicating no sort.

Default value: "ascending"

Note: null is not supported for row and column.

time_unit: Option<TimeUnit>

Time unit (e.g., year, yearmonth, month, hours) for a temporal field. or a temporal field that gets casted as ordinal.

Default value: undefined (None)

title: Option<String>

A title for the field. If null, the title will be removed.

Default value: derived from the field’s name and transformation function (aggregate, bin and timeUnit). If the field has an aggregate function, the function is displayed as part of the title (e.g., "Sum of Profit"). If the field is binned or has a time unit applied, the applied function is shown in parentheses (e.g., "Profit (binned)", "Transaction Date (year-month)"). Otherwise, the title is simply the field name.

Notes:

1. You can customize the default field title format by providing the [fieldTitle property in the config or fieldTitle function via the compile function’s options.

2. If both field definition’s title and axis, header, or legend title are defined, axis/header/legend title will be used.

mark_prop_def_with_condition_type: Option<Type>

The encoded field’s type of measurement ("quantitative", "temporal", "ordinal", or "nominal"). It can also be a "geojson" type for encoding ‘geoshape’.

value: Option<PurpleValue>

A constant value in visual domain.
