aggregate Field

Causes the grid to calculate aggregate values on the column and place them in the column footer cell or group header and footer rows. Possible values are: "none", "count", "sum", "average", "min", "max", "std", "stdPop", "var", "varPop" and "custom".

Syntax

Javascript (Usage)
var instance; // Type: wijmo.grid.IC1FieldOptions; var value; // Type: string value = instance.aggregate;

Javascript (Usage)

var instance; // Type: wijmo.grid.IC1FieldOptions;
var value; // Type: string
value = instance.aggregate;

Javascript (Specification)
var aggregate : string;

Example

Javascript

$("#element").wijgrid({ columns: [{ aggregate: "count" }]});

Remarks

Possible values are: "none": no aggregate is calculated or displayed. "count": count of non-empty values. "sum": sum of numerical values. "average": average of the numerical values. "min": minimum value (numerical, string, or date). "max": maximum value (numerical, string, or date). "std": standard deviation (using formula for Sample, n-1). "stdPop": standard deviation (using formula for Population, n). "var": variance (using formula for Sample, n-1). "varPop": variance (using formula for Population, n). "custom": custom value (causing grid to throw groupAggregate event). If the showFooter option is off or grid does not contain any groups, setting the "aggregate" option has no effect.
