Type alias AggregateSpecMap<T>

Several aggregates by key. In aggregateColumns the key names the result (and is the default property path); in a footer (AreaModelAggregateFooter) the key is the property of the column that shows the result.

Example

const specs: AggregateSpecMap<Order> = {
  quantity: "sum",
  total: "sum",
  customer: "countDistinct",
  avgTotal: { aggregator: "avg", value: "total" }   // a key without a column: only in the results
};
