I am trying to create a graph which displays deltas from the previous week and current week. In terms of delta, I would like to display the events that showed up last week, but not the current week AND the events that showed up this week, but not last week.
In each event there is an "ID" field. I would use the "ID" field to get the deltas. If there are duplicate ID's, these events would be omitted from the graph. I've looked into aggregated unique counts and json input, but could not find a solution. Any help would be appreciated.
