Ticket #1313 (new wish)
Expand functionality of groupby widget.
|Reported by:||echlebek||Owned by:||echlebek|
I'd like to add some functionality to this widget.
- The ability to create multiple groupings per attribute.
- A per-attribute boolean property which causes the aggregator to only consider unique values.
- The ability to group into lists and sets.
The first and second ideas are fairly easy to achieve. The second idea would naturally necessitate an ungrouping widget to deal with attributes that are collection objects. I'm also not sure how well the Orange data model would handle these types of objects.
