Hello,
I created a new DataType which is called AttributeValue. The class Attribute extends DataCell and implements AttributeValue, DoubleValue, BoundedValue. It has also some additional data besides the value, which I need for my visualization node.
It works great, but there is a problem with the GroupBy Node. When I use it with the “Mean” aggregation method it throws away my AttributeCell (with all the additional data) and creates a new DoubleCell.
Is there a possiblity to avoid the creation of the DoubleCell? Why doesn’t the GroupBy node use my AttributeValue for calculating the mean value?
Thanks for any response
