Graph of Lines Numbered

How do you add a text to a graph of x,y,z with numbered at each point such as 1,2,3,4,5...

 void Start()
     {
        for(int i = 0; i < 10; i++)
         {
             Vector3 end = new Vector3(10, 0, 0);
             Vector3 oneStart = default;
             int checkNum = Vector3.Distance(oneStart, end);
             if(checkNum < 10)
             {
                 text.text = checkNum.ToString();
             }
             }
         }

still cannot find out how to make a line graph with numbers on it

  for (int i = 0; i < names.Length; i++)
         {
             transform.position = new Vector3(i, 0, 0);
             names[i].text = i.ToString();
             Debug.Log(names[i]);
 
         }
