Struct vega_lite_3::SortEncodingSortField

pub struct SortEncodingSortField {
    pub field: Option<Field>,
    pub op: Option<AggregateOp>,
    pub order: RemovableValue<SortOrder>,
}

A sort definition for sorting a discrete scale in an encoding field definition.

Fields

field: Option<Field>

The data field to sort by.

Default value: If unspecified, defaults to the field specified in the outer data reference.

op: Option<AggregateOp>

An aggregate operation to perform on the field prior to sorting (e.g., "count", "mean" and "median"). An aggregation is required when there are multiple values of the sort field for each encoded data field. The input data objects will be aggregated, grouped by the encoded data field.

For a full list of operations, please see the documentation for aggregate.

Default value: "sum" for stacked plots. Otherwise, "mean".

order: RemovableValue<SortOrder>

The sort order. One of "ascending" (default), "descending", or null (no not sort).
