Customized domain values in the form of constant values or dynamic values driven by a parameter.

Constant domain for quantitative fields can take one of the following forms:

A two-element array with minimum and maximum values. To create a diverging scale, this two-element array can be combined with the domainMid property.
An array with more than two entries, for Piecewise quantitative scales.
A string value "unaggregated", if the input field is aggregated, to indicate that the domain should include the raw data values prior to the aggregation.

Constant domain for temporal fields can be a two-element array with minimum and maximum values, in the form of either timestamps or the DateTime definition objects.
Constant domain for ordinal and nominal fields can be an array that lists valid input values.
To combine (union) specified constant domain with the field's values, domain can be an object with a unionWith property that specify constant domain to be combined. For example, domain: {unionWith: [0, 100]} for a quantitative scale means that the scale domain always includes [0, 100], but will include other values in the fields beyond [0, 100].
Domain can also takes an object defining a field or encoding of a parameter that interactively determines the scale domain.

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

Source:: vega-lite.scala

The strategy to use for resolving overlap of axis labels. If false (the default), no overlap reduction is attempted. If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

Extending the domain so that it starts and ends on nice round values. This method typically modifies the scale’s domain, and may only extend the bounds to the nearest round value. Nicing is useful if the domain is computed from data and may be irregular. For example, for a domain of [0.201479…, 0.996679…], a nice domain might be [0.2, 1.0].

For quantitative scales such as linear, nice can be either a boolean flag or a number. If nice is a number, it will represent a desired tick count. This allows greater control over the step size used to extend the bounds, guaranteeing that the returned ticks will exactly cover the domain.

For temporal fields with time and utc scales, the nice value can be a string indicating the desired time interval. Legal values are "millisecond", "second", "minute", "hour", "day", "week", "month", and "year". Alternatively, time and utc scales can accept an object-valued interval specifier of the form {"interval": "month", "step": 3}, which includes a desired number of interval steps. Here, the domain would snap to quarter (Jan, Apr, Jul, Oct) boundaries.

Default value: true for unbinned quantitative fields without explicit domain bounds; false otherwise.

For color ranges, this property allows interpolation in alternative color spaces. Legal values include rgb, hsl, hsl-long, lab, hcl, hcl-long, cubehelix and cubehelix-long ('-long' variants use longer paths in polar coordinate spaces). If object-valued, this property accepts an object with a string-valued type property and an optional numeric gamma property applicable to rgb and cubehelix interpolators. For more, see the d3-interpolate documentation.

Default value: hcl

A string indicating a pre-defined named scale range (e.g., example, "symbol", or "diverging").
For continuous scales, two-element array indicating minimum and maximum values, or an array with more than two entries for specifying a piecewise scale.
For discrete and discretizing scales, an array of desired output values or an object with a field property representing the range values. For example, if a field color contains CSS color names, we can set range to {field: "color"}.

Notes:

For color scales you can also specify a color scheme instead of range.
Any directly specified range for x and y channels will be ignored. Range can be customized via the view's corresponding size (width and height).

Source:: vega-lite.scala

The type of scale. Vega-Lite supports the following categories of scale types:

Continuous Scales -- mapping continuous domains to continuous output ranges ("linear", "pow", "sqrt", "symlog", "log", "time", "utc".
Discrete Scales -- mapping discrete domains to discrete ("ordinal") or continuous ("band" and "point") output ranges.
Discretizing Scales -- mapping continuous domains to discrete output ranges "bin-ordinal", "quantile", "quantize" and "threshold".

Default value: please see the scale type table.

Source:: vega-lite.scala

A string indicating a color scheme name (e.g., "category10" or "blues") or a scheme parameter object.

Discrete color schemes may be used with discrete or discretizing scales. Continuous color schemes are intended for use with color scales.

For the full list of supported schemes, please refer to the Vega Scheme reference.

"union" -- each cell contains its own brush, and points are highlighted if they lie within any of these individual brushes.
"intersect" -- each cell contains its own brush, and points are highlighted only if they fall within all of these individual brushes.

Default value: global.

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 string indicating an encoding channel name to sort by (e.g., "x" or "y") with an optional minus prefix for descending sort (e.g., "-x" to sort by x-field, descending). This channel string is short-form of a sort-by-encoding definition. For example, "sort": "-x" is equivalent to "sort": {"encoding": "x", "order": "descending"}.
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.

Source:: vega-lite.scala

The type of measurement ("quantitative", "temporal", "ordinal", or "nominal") for the encoded field or constant value (datum). It can also be a "geojson" type for encoding 'geoshape'.

Vega-Lite automatically infers data types in many cases as discussed below. However, type is required for a field if: (1) the field is not nominal and the field encoding has no specified aggregate (except argmin and argmax), bin, scale type, custom sort order, nor timeUnit or (2) if you wish to use an ordinal scale for a field with bin or timeUnit.

Default value:

For a data field, "nominal" is the default data type unless the field encoding has aggregate, channel, bin, scale type, sort, or timeUnit that satisfies the following criteria:

"quantitative" is the default type if (1) the encoded field contains bin or aggregate except "argmin" and "argmax", (2) the encoding channel is latitude or longitude channel or (3) if the specified scale type is a quantitative scale.
"temporal" is the default type if (1) the encoded field contains timeUnit or (2) the specified scale type is a time or utc scale
ordinal"" is the default type if (1) the encoded field contains a custom sort order, (2) the specified scale type is an ordinal/point/band scale, or (3) the encoding channel is order.

For a constant value in data domain (datum):

"quantitative" if the datum is a number
"nominal" if the datum is a string
"temporal" if the datum is a date time object

Note:

Data type describes the semantics of the data rather than the primitive data types (number, string, etc.). The same primitive data type can have different types of measurement. For example, numeric data can represent quantitative, ordinal, or nominal data.
Data values for a temporal field can be either a date-time string (e.g., "2015-03-07 12:32:17", "17:01", "2015-03-16". "2015") or a timestamp number (e.g., 1552199579097).
When using with bin, the type property can be either "quantitative" (for using a linear bin scale) or "ordinal" (for using an ordinal bin scale).
When using with timeUnit, the type property can be either "temporal" (default, for using a temporal scale) or "ordinal" (for using an ordinal scale).
When using with aggregate, the type property refers to the post-aggregation data type. For example, we can calculate count distinct of a categorical field "cat" using {"aggregate": "distinct", "field": "cat"}. The "type" of the aggregate output is "quantitative".
Secondary channels (e.g., x2, y2, xError, yError) do not have type as they must have exactly the same type as their primary channels (e.g., x, y).

Controls whether data values should be toggled (inserted or removed from a point selection) or only ever inserted into multi selections.

One of:

true -- the default behavior, which corresponds to "event.shiftKey". As a result, data values are toggled when the user interacts with the shift-key pressed.
false -- disables toggling behaviour; as the user interacts, data values are only inserted into the multi selection and never removed.
A Vega expression which is re-evaluated as the user interacts. If the expression evaluates to true, the data value is toggled into or out of the multi selection. If the expression evaluates to false, the multi selection is first clear, and the data value is then inserted. For example, setting the value to the Vega expression "true" will toggle data values without the user pressing the shift-key.

Default value: true

The type of measurement ("quantitative", "temporal", "ordinal", or "nominal") for the encoded field or constant value (datum). It can also be a "geojson" type for encoding 'geoshape'.

Default value:

For a data field, "nominal" is the default data type unless the field encoding has aggregate, channel, bin, scale type, sort, or timeUnit that satisfies the following criteria:

"quantitative" is the default type if (1) the encoded field contains bin or aggregate except "argmin" and "argmax", (2) the encoding channel is latitude or longitude channel or (3) if the specified scale type is a quantitative scale.
"temporal" is the default type if (1) the encoded field contains timeUnit or (2) the specified scale type is a time or utc scale
ordinal"" is the default type if (1) the encoded field contains a custom sort order, (2) the specified scale type is an ordinal/point/band scale, or (3) the encoding channel is order.

For a constant value in data domain (datum):

"quantitative" if the datum is a number
"nominal" if the datum is a string
"temporal" if the datum is a date time object

Note:

Data type describes the semantics of the data rather than the primitive data types (number, string, etc.). The same primitive data type can have different types of measurement. For example, numeric data can represent quantitative, ordinal, or nominal data.
Data values for a temporal field can be either a date-time string (e.g., "2015-03-07 12:32:17", "17:01", "2015-03-16". "2015") or a timestamp number (e.g., 1552199579097).
When using with bin, the type property can be either "quantitative" (for using a linear bin scale) or "ordinal" (for using an ordinal bin scale).
When using with timeUnit, the type property can be either "temporal" (default, for using a temporal scale) or "ordinal" (for using an ordinal scale).
When using with aggregate, the type property refers to the post-aggregation data type. For example, we can calculate count distinct of a categorical field "cat" using {"aggregate": "distinct", "field": "cat"}. The "type" of the aggregate output is "quantitative".
Secondary channels (e.g., x2, y2, xError, yError) do not have type as they must have exactly the same type as their primary channels (e.g., x, y).
