I am trying to get best statical method to show performance of accumulative revenue by customer compare week over week. Currently I have about over 100 customer charts compare by hour from same day last week vs today. But what would the best way to show revenue different by hour if I want to put it all in one chart ( assume 100 customers ) ? would % change below be the best indicator ? or is there a better way to show it in one chart ?
%diff = (cum current rev / cum previous revenue ) - 1
