Aggregation Plot Errors

Aggregation plotting does not plot the same set of points for every student. See here for a sample of what students saw:

Reduced test case here: aggregation • Activity Builder by Desmos Classroom

I think what’s probably happening is that aggregation does not keep good track of the order in which its data is registered, meaning it sometimes plots (x,y) pairs that are not true pairs, but rather come from somewhere in the list of x’s and y’s.

Needless to say it’s a problem for plotting. Thoughts?
