Sometimes we do some tests with product prices for different channels, etc.
I tinkering with my report, but didn't achieve anything that would be close to show if one product/channel cannibalizes the other. How would you approach it? I believe I have all data needed to do that, but I don't know how.
Specific example, we made product A more expensive when paid through channel A. It's share in overall profit for given week dropped by 2%. What would be the best way to visualize which other products cannibalized the money previously spent in channel A on that product?
