Title. I have the main math stuff, but I’m stuck at converting numbers into properly usable scale positions for the Y coordinate. How would I do this?
Thanks!!
Do you mean you want to place Parts in game to create a graph?
You could place a Part on your X or Z axis at evenly spaced intervals and do the “main math stuff” to calculate the Y Position. Then you could use RopeConstraints or Beams to join the Parts.

I’m trying to do it in GUI. The only thing I don’t know how to do is calculate the Y position, that’s where I’m stuck
Since gui’s start from top-left, you’ll have to use the 4th quadrant’s topleft corner as the origin, that way over 0 will go in the top half of the graph, and -1 will go towards the bottom half of the graph.
I don’t think this really helps me though. I’m trying to convert the numbers into numbers usable for UDim2 Scale.
It does, that’s meant to be for scale.

I don’t understand how this works… Why does graph use a function as a parameter? Sorry if I sound horrendously stupid right now.
It uses a function as a parameter to return a value. When you call it, e.g
graph(function(x)
return x^2
end, Color3.new(1,1,1))
the x value is fed through the parameters when calling func().
I don’t really get why this is needed…
