plot transient solution

Hello, I have a problem to plot my transient solution and I hope someone can help me.
I am solving a transient two-dimensional advection-diffusion problem through the transport of diluted species module. The wind speed and diffusivity both vary in time, but not continuously, they assume constant values for each interval of time. To include this variation in my model, I criated two steps time, each one corresponding to the desired variation for the wind speed and eddy diffusivity. When I try to see the evolution of my solution in time, I just can see that corresponding to the last step time. It was if the former was erased by comsol.
Any tip is appreciated.
Thanks,
Joana.

In addition to my previous question, I would like to know if the only (or maybe the best) way to solve this problem is creating a function to calculate the velocity and the diffusion in matlab and make a livelink with comsol.
