addCalculatedMeasure

addCalculatedMeasure(measure: Object)

[starting from version: 2.3]

This API call adds a calculated measure.

Calculated measure must have the formula property. You can create as many calculated measures for one report as you need, there is no limit to the number of calculated measures.

When you save the report, all the calculated measures will be saved as well and loaded when the report is restored.

Learn more about calculated measures in this guide: Calculated values.

Note that you can add calculated measures only for reports based on "json", "csv", and "api" data source types.

Parameters

measure - the object that describes measure. This object can have the following properties:

Property/Type	Description

A measure can be addressed using its unique name and an aggregation function. For example, sum("Price") or max("Order").

caption String	optional The measure’s caption.
grandTotalCaption String	optional The measure’s grand total caption.
active Boolean	optional Indicates whether the measure will be selected for the report (true) or not (false). active: false can be useful if the measure has non-default properties, but should not be selected for the grid or the chart.

Example

The following example shows the calculated measure Average Quantity which is calculated as sum("Quantity")/count("Quantity") and will be added to the list of available measures but not selected for the report (active: false):

let measure = {
  formula: 'sum("Quantity")/count("Quantity")',
  uniqueName: "Average Quantity",
  caption: "Average Quantity",
  grandTotalCaption: "Total Quantity",
  active: false
};

flexmonster.addCalculatedMeasure(measure);
