Using Sum function for aggregate measure

The sum function can be used with a numeric attribute to compute total trends across aggregated data groups.

For example, it can be used to measure total people affected, total votes, and total cost across other data properties.

• If you are using a time-series attribute, you can also specify which time-key to use as the basis for aggregation measurements.

Constraints

• Stacked charts cannot be used with Sum function on a data attribute with any negative values.
