title: Excel line graph with data range
body: <p>I have a problem with excel line graph. I want to line graph, but my data set contains data range rather than exact value. For example;</p>
  
  <p>variables x,y;</p>
  
  <p>x = {1,2,3,4} and y = {2-4, 8-16, 7-3.5 , 2-5}</p>
  
  <p>when x = 1, y is in the range of 2 and 4 and goes on like that. I hope I can identify the problem. How can I plot graph for this kind of a data set? Or Can I plot with excel?</p>
  
  <p>Thanks in advance.</p>
