HEllo,
I want to create an attribute (distance) between two points. I am using AttributeCreator to do it. Here is the code:
@Evaluate(@sqrt((@Value(feature[+1].y)-@Value(y))*(@Value(feature[+1].y)-@Value(y))/(@Value(feature[+1].x)-@Value(x))*(@Value(feature[+1].x)-@Value(x))))The problem is that I want to calculate it only between points where lineID is the same. How can I add a kind of group by?
Thanks
