Apologies for the delay in responding.

I would look at Example 17, the stripchart demo to see if something like 
that might work for you. Otherwise I think you'd just have to try your 
use case and see if it can be done fast enough. There is a function 
called plclear() that you can use to clear the plot so that you don't 
have to remake everything.
