Aggregate

Represents the PivotGrid aggregate object. Applicable for local data binding.

ts

const sumAggregate: Aggregate = {
    init: (data) => { data.sum = ('sum' in data) ? data.sum : 0; },
    accumulate: (data, value) => { data.sum += value; },
    merge: (src, dest) => { dest.sum += src.sum; },
    result: data => data.sum,
    format: (value: number) => value.toFixed(2)
};

Name	Type	Default	Description
accumulate	(data: any, value: any) => void		The accumulate function will be called for every value that needs to be aggregated.
format	(value: any) => string		The format function will be called when the value returned from the result function needs to be formatted.
init	(data: any) => void		The init function initializes the variable where the aggregated data will be stored and returns it in the passed data object. The init function will be called every time before calling accumulate and merge functions.
merge	(src: any, dest: any) => void		The merge function will be called when two aggregated data objects needs to be merged into one.
result	(data: any) => any		The result function will be called when the aggregated value needs to be extracted from the data object.
