Struct EncodingSortField 

pub struct EncodingSortField {
    pub field: Option<Field>,
    pub op: AggregateOp,
    pub order: Option<VgComparatorOrder>,
}

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: AggregateOp

An aggregate operation to perform on the field prior to sorting (e.g., "count", "mean" and "median"). This property is required in cases where the sort field and the data reference field do not match. 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.

order: Option<VgComparatorOrder>

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