The best way I can explain the graph is:
1. look at the line and mark a point where ever you see the line goes through a point (look at picture bellow)
2. best example on your graph is (40, 20): April 40...March 20
3. you will notice that march will always sell half the number of april's sale
another example in your graph:
april sold 10....the line seem to be a 10, 5.....march sold 5
