Placing points on frames in right position issue (Collatz Conjecture Visulization)

Okay, so I saw a new veritasium video: The Simplest Math Problem No One Can Solve - Collatz Conjecture - YouTube about the Collatz Conjecture.

Essentially: get a number.
2 rules:
If the number is odd: Multiply it by 3 and add 1.
If the number is even: Divide by 2.
It’s theorized, that it will always get to the number 1, and since one is odd, multiply it by 3, and add 1. You have 4. Then divide by 2, which is 2, it’s even, so divide by 2 again, you get one. Infinite loop.
I decided I wanted to visualize this in studio, with screen gui’s, because why not?

But the problem is, I can’t seem to position is properly. The higher the number is. The lower it goes, but I want it to be the opposite, and I can’t seem to get it to position correctly.

Here’s my script. It’s super simple, but idk what to do.

local MainFrame = script.Parent.MainFrame
local Format = MainFrame.Format
local function Even(num)
	return (num % 2 == 0)
end

script.Event.Event:Connect(function(numberToStart)
	for i,v in pairs(MainFrame:GetChildren()) do
		if v.Name ~= "Format" then
			v:Destroy()
		end
	end
	local NumbersIterated = 1
	local Number = numberToStart
	while true do
		wait()
		if Even(Number) then
			Number /= 2
		elseif not Even(Number) then
			Number = (Number*3)+1
		end 
		print(Number)
		local NewFormat = Format:Clone()
		NewFormat.Name = tostring(Number)
		NewFormat.Text = tostring(Number)
		NewFormat.Position = UDim2.new(NumbersIterated/100,0,Number/1000,0)
		NewFormat.Visible = true
		NewFormat.Parent = MainFrame
		if Number == 1 then
			print("It reached one.")
			break
		end
		NumbersIterated += 1

	end
	
	
end)

My goal is to eventually get something like this. I’ll work on the lines later.

This is just because the top left corner of a roblox UI element is (0,0). If you want to reverse it on the Y axis just subtract the position you want from 1 since you’re just working with Scale.

NewFormat.Position = UDim2.fromScale(NumbersIterated/100, 1 - Number/1000)

Awesome. Works perfect now. I’m gonna play around with the numbers a bit to make sure they look good.
