Add a 2y button to the Graphs tab on the lower R so we don't have to scale manually for >1 to <5 years.
If you need more real estate on the page to do this, eliminate some (or all) of the day buttons. They are useless for Midnight Cowboys, but others can easily scale to any usable view manually using only 1, 3 and 5 d(ay) buttons. You'd even have room to add a 2 w(eek) button, if desired. Change the 5 and 10 y(ear) buttons to automatically show weekly charts to speed up loading.
