create player Y position graph?

hi there, I had been able in creating a player Y position indicator that can display how high is the humanoid from the ground. which is beneficial in determining the success factor in the game I am creating. kind of like tower of hell.

here is the code that I created that shows the player's height from the ground in the leaderstat. and here is the screenshot of the said leaderstat

local function OnPlayerJoin(player)

     repeat wait() until player.Character

    local leaderstats = Instance.new("Folder")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local Height = Instance.new("IntValue")
    Height.Name = "Height"
    Height.Parent = leaderstats
    while wait() do Height.Value = (player.Character.HumanoidRootPart.Position.Y - 8) end


end

game.Players.PlayerAdded:Connect(OnPlayerJoin)

but right now I am trying to turn this number info into a graph like tower of hell did. any suggestion of how I can turn it in like a graph in Tower of Hell game did?

here is the TOH screenshot. graph
