Enum vega_lite_4::Field
source · pub enum Field {
RepeatRef(RepeatRef),
String(String),
}
Expand description
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.
See also: field
documentation.
Notes: 1) 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. 2) field
is not
required if aggregate
is count
.
The data field to sort by.
Default value: If unspecified, defaults to the field specified in the outer data reference.
