Can I get help getting these randomized points from working in the graph to working in the activity with the random generator and a button press? points with rng • Activity Builder by Desmos

I’m not sure if it’s actually documented anywhere, but you can use a second parameter in Shuffle that forces it to re-randomise whenever that second value changes. So if you use c_1=shuffle(A,b) or c_1=shuffle(A,m), whenever the button is pressed and b or m are updated, the list will be reshuffled a…

I think one of my issues with this is when I write in in the graph CL, it shows up as a point, rather than a list of points, so only one gets plotted and randomly changes. I don’t now how to get the list to the CL?

You can’t manipulate lists in the CL. If your aim is to randomize using CL, you can set a number in the graph to a button press or a random number using the random number generator. Using that number, b in @pisquared’s example, to shuffle or reshuffle the list.

In that case, I’m not sure I fully understand what you’re trying to achieve. At the minute, you have semi-random points generated by being a random distance above or below a randomly-generated line of best fit. If you use shuffle(A,b) or similar then the random distances will update each time the li…

Okay, I am missing something. Thank you both for your insight!

Okay I understand now, I got it to work the shuffle(A,b), thing, thank you so much for your help! …and sorry for not understanding sooner, all of what I’ve learned has been from direct example.

I don’t understand any of this, and can’t find any information on it anywhere. I am sorry, thank you for your patience with me. So, if I have a list N=[-5…5] , then n_1=shuffle(N) just shuffles those 11 elements. What if I wanted to draw from those 11 elements 30 times?

I mean make a new list of 30 elements randomized from the integers in the first list.

Okay, previous post from Daniel [image] Generating random integers (without repeats) L=unique( [1...1000].random(40,s_eed) )[1...10] L=( [-5…5].random(30,s_eed)?

Okay, I got it now, thank you so much for all your help on this forum!!

Glad you got it sorted. You can also take advantage of the syntax random(list, n, seed) - for instance: L=random([-5...5],30,s_eed) There’s some more detail available here (although not all syntaxes are listed): [image] Statistics Introduction | General Statistical Functions | Statisti…
