So for this, it will be helpful if you understand a bit of multivariable calculus. Since the plot will not only be a function of time, but also a function of space (x,t) so your function now has two variables. We know this for a fact, because we encounter it in our daily lives. (at least we perceive it to be such a fact) Now looking at standard equation of a wave :
We see how a function might change as x, and t changes. But much of the time, one parameter may seem rather arbitrary, and that parameter may be time.
I know that I am getting a bit off topic, but use the standard equations of a wave to guide you on what you want to plot. I believe Wolfram alpha has the ability to plot functions of several parameters if I am not mistaken. Experiment, and have a little fun with it. :)
