Creating a graph

I’m trying to create a graph, with dots and lines. Got the dots done, but can’t get the lines connecting them figured out.

local function CreateGraph()
	local Size = Graph.Dates.UIListLayout.Padding.Offset
	
	-- Create dots
	for i = 1, 7 do
		local NewDot = DotTemplate:Clone()
		NewDot.Name = "Dot"
		NewDot.Position = UDim2.new(0.5, 0, Rates[i] / MAX, 0)
		
		NewDot.Parent = Graph.Dates[i]
	end
	
	-- Create lines
	for i = 1, 7 do
		local Line1 = Graph.Dates:FindFirstChild(i)
		local Line2 = Graph.Dates:FindFirstChild(i + 1)
		if not Line1 or not Line2 then continue end
		
		local NewLine = LineTemplate:Clone()
		
		local XLength = Line1.Dot.AbsolutePosition.X - Line2.Dot.AbsolutePosition.X
		local YLength = Line1.Dot.AbsolutePosition.Y - Line2.Dot.AbsolutePosition.Y
		
		local Mag = (
			Vector2.new(Line1.Dot.AbsolutePosition.X, Line1.Dot.AbsolutePosition.Y) 
			- Vector2.new(Line2.Dot.AbsolutePosition.X, Line2.Dot.AbsolutePosition.Y)
		)
		local CenterPosition = (Line2.AbsolutePosition + Line1.AbsolutePosition) / 2
		NewLine.Rotation = math.atan2(YLength, XLength) * 180 / math.pi
		
		NewLine.Position = UDim2.new(
			0,
			CenterPosition.X,
			0,
			CenterPosition.Y
		)
		NewLine.Size = UDim2.fromOffset(Mag.Magnitude, 4)
		
		NewLine.Parent = Graph.Lines
	end
end

It ends up creating the lines on the bottom left of the screen

I’m no genius in Vector2 Frame Size and position but Here I’ve have given you a idea on how it’s going to work

local table = {}
local firstval = 0
local secondval = 1

for index = 1,7 do
firstval = firstval + 1
table.insert(table,firstposition)
secondval = secondval + 1
table.insert(table,secondposition)
drawgraph.Size = Vector2.new(1,(table[firstval] - table[secondval]).Magnitude)
end

You can align the CFrame just how you did for the one now

In the CenterPosition line, did you mean to use Line2.Dot or Line1.Dot? Because that’s the only pattern I’m seeing that is broken, you’ve used Line.dot everywhere besides there.
