The waterfall chart below details the prize money distribution for the primary events at the 2015 US open. The total is $38.4M (excludes qualifying events) of which the singles events take $33M.
The waterfall or cascade chart is an effective way help readers understand the primary components: how much money is allocated to each event (bars), and how much money is allocated to the winners of each event (segments). Within each vertical bar, the horizontal segments highlight the prize money the winners take home versus all the other players. On average the winners of each event walk away with about 10% of the total prize money for that event.
