Moving back and forth between old datasets and new datasets? I know there are versions of the data but I'm clicking on them and it seems it is just all the new data?
Are you trying to do the comparison in the same project? This sort of comparison can be done by a join/look up provided there is a primary key like an ID that is common between the two datasets.
This is when I've built out a project and trying to flip back and forth between months. So the old data set would be June and the new data set is July but I want to see June and compare it to July.
