If the intent is to copy the example exactly then I'd think the imageData
would be the same. But I'd use location data as others have suggested. Get
the end points of the line graphic and loop through a list of correct
points to compare against.

Thanks for the replies.
I just put it on the forum as well and attached an image with it to get a
better idea of what I want to do.

William,
My basic suggestion is that you use the location data of each connected
dot, rather than the image data.
Good luck,

path are also connected in another path which may have them connected in a
different order. Seems you could just loop through each dot in the
reference path, then see if the same dots are included in the user’s path.
You would need to include a name for each reference point, of course.
That’s if I understand your problem correctly.
