Create lists off elemente with same Y value

[RoelB]

Hi all,

I’m trying to make different lists of elements that share the same Y value.
This is what’s I’ve tried but now I’m a little stuck.

Thank you!

@RoelB ,

you can use groupByKey node to sort your points

or do want to set specific points by other points(Y) ?

I just want to create a list for every unique Y value of the elements.
grouping doesn’t work. it also gives me list of y values not a true or false so i can filter the elements.

@RoelB ,

or like this

you could also create new points

Thanks, but it’s not about the point.
It’s about sorting element by coordinates.

Hola Amigo @RoelB buenas. you can always group items using his index like this, you can also sort by value first if that is you are looking for, i let you the image i hope this works for you!

Thank you.

Every unique Y value needs to create his own list with elements that contain this Y value.
In the example above, I only collect the location of those elements.

@RoelB ,

than it is group by key

… than will have like List intersection
