How to read port 1D result in CST

I'd asked about result of 1D port at cst. For the port mention time signal, and for the x axis is time/s. The number on x axis for example 2e-006, 1,2e-007. I dont know what that means and how to read it. I only onow that i1 is for incident wave, and o1.1 is for reflected wave. But i dont know how to read the result. Anyone can help.me please
