A cumulative distribution function for data on a regular time step, e.g., hourly weather data, is simply a plot of the data sorted from low to high on the X axis, where the Y axis is normalized as the cumulative frequency going from 0 to 1. I've attached a slide from an old Powerpoint presentation showing some CDFs from a talk I gave in 2009.
