Your graph should look like this though... It's 30¢ every min so every 5 mins is a $1.50 increase, every 10 mins is a $3 increase. And I think your graph is a little wrong too because the increase starts after 40mins so the price should have increased at 45mins, but your $5 is inclusive of the 45th min...
