Cumulative Sum feature replaces points' values with the following formula: sum of all previous points' values + current point's value. Works only for points in a visible range. Adds the cumulativeSum field to each point object that can be accessed e.g. in the tooltip.pointFormat.

With dataGrouping enabled, default grouping approximation is set to sum.
