Hi,

Thanks for help.

The ecdf has jumps of 1/n but I need jumps of 1. How do I do this? if I can do this then I think Ic an plot the data properly. I am plotting epidemic simulation and want to plot my 2 processes Infection and Symptoms (after incubation) on the same chart to compare them.

Atul.
