Returns a copy of the BreakdownSet with all the metadata values multiplied by the supplied number. This can be useful when a metric value is being scaled to convert from seconds to minutes or hours; the metadata of the metric can be similarly scaled.
var minutes = metrics.get('Time Spent').getLatest();
var timeInHours = minutes / 60;
var meta = timeSpent.breakdown().scale(1/60);
return {
value : timeInHours,
breakdown : meta
}
