As far as I know, you cannot see this directly inside Pigment but you can get a sense of history for updates related to pivots, layouts, aggregators, and formatting performed on a view/metric/table, thanks to the Audit Log and EventType like “ViewUpdated”, “MetricUpdated”, ”TableUpdated”.
However, it won’t give you the exact changes applied, you will only know that a given view/metric/table was updated. You can find more info regarding Audit Log and Event Types here :
