"lock" randomized values for snapshots?

Learning so much about CL! I have the following screen in an activity:

I am using random values in the graph to generate the x and y intercepts, just for a little bit of added pizazz. :sunglasses: :grin:

I am brand new to AB so I did a bit of test-running today. When I took some snapshots, all looked fine from the dashboard:

But when I actually ā€œpresentā€, the graph is showing the default (?) values, not the randomized values, for the points. :confused: Any fix for this? In this particular activity, it isnā€™t really crucial that I randomize those values, but in some other context I might not want to give that up.

For some reason, when you use random in a graph, it only does it once and then it never randomizes again. Try using the CL for your randoms instead. Something like:

r = randomGenerator(expInput2.submitCount)
number("a"): r.int(-4,4)
...

Iā€™m using the submitCount to seed the generator, so that, again, it doesnā€™t calculate just once.

Thanks for the help! I actually had to remove the submitCount, as I donā€™t want it to re-calculate the points, I want to compute the points once per student but randomly across students. With that in the random generator, it was re-computing the random points when the student clicked ā€œsubmitā€, which resulted in the correct answer now being wrongā€¦ lol!

Itā€™s working perfectly now, and the randomly selected points are ā€œstickingā€ for the snapshots! Thanks so much!! :grin:
