Aggregate/summarization info missing in dataViews

Hello everyone!
I am using Table DataViewMapping in my custom visual. I am facing an issue where I can't find any info regarding the aggregation/summarization (Average, Sum, Count, Median etc) applied to a column in the dataViews. When there is only a single column (single numerical value), the correct summary is applied and the value is correct. However, when broken down by categories or groups, the summary info is lost. Is there any info inside the VisualUpdateOptions recieved by the update() method of the visual, regarding the summary applied to a column?
