I have a bar chart and a table, which both have exactly the same formula. So for every combination of carrier and week I make, the bar chart and the table show the same data. But for some reason, if I select BTS and week 2014-12 of 2014-13, the data shows a lower percentage in my bar chart. My overall performance for week 12 and 13 is also lower as a result of this. Can anybody help me with this?
