How do you force my 3D graphing system to graph between -71 and 71?
Hello.
I made my own graphing system using blocks and my own equations. I've also made my own custom 3D axes that range from -71 to 71 on all axes. The only problem is that when I try to graph something, the graph goes out of the y-axis range. I have used math.clamp(partPosY, -71, 71) to fix it, but no luck.
Here are some screenshots (Couldn't convert them to links for some reason...):

Graph went out of range on the y-axis (min:71, max:71) https://gyazo.com/5772e2b944d13b58a48d803bd4d324c6
Is there a way to accomplish this? Here is my code snipplet:
1 | function grp(part) |
2 | local finalF = Vector3.new(part.Position.X, (part.Position.X^3*part.Position.Z+part.Position.Z^3*part.Position.X)/2000, part.Position.Z) |
3 | part.BodyPosition.Position = Vector3.new(finalF.X, finalF.Y, finalF.Z) |
4 | end |

In an ironic twist of fate, I did something similar to generate smooth terrain from an array of 2d points just the other day :p

Try separating your functions:
01 | local calcy = function(x, z) |
02 | return (x^2)+(z^2); |
03 | end |
04 |
05 | local graph = function(x, y, z) |
06 | local point = Instance.new("Part", game.Workspace); |
07 | point.Size = Vector3.new(1, 1, 1); |
08 | point.CFrame = CFrame.new(x, y, z); |
09 | end |
10 |
11 | graph(1, math.clamp(calcy(1, 2), -71, 71), 2); |
If the name of the game is to only graph points within a certain limit, there are two good ways of doing it.
The best way would be to alter the graph() function as such:
1 | local graph = function(x, y, z, min, max) |
2 | if((y >= min) and (y <= max))then |
3 | local point = Instance.new("Part", game.Workspace); |
4 | point.Size = Vector3.new(1, 1, 1); |
5 | point.CFrame = CFrame.new(x, y, z); |
6 | end |
7 | end |
The other option would be to do this:
01 | local points = {}; |
02 |
03 | -- normal body, but insert all instanced parts into table of points, then destroy any points out of bounds |
04 |
05 | graph(1, math.clamp(calcy(1, 2), -72, 72), 2); |
06 | for a, x in pairs(points) do |
07 | if((x.Position.Y > 71) or (x.Position.Y < -71))then |
08 | x:Destroy(); |
09 | end |
10 | end |
