Creating multiple graphs and handling a single stream in each would work, but each graph would end up reading and parsing the while CTF trace, which is not great. If you streams are in a data file of their own, you could move them to their own directory, each with a copy of the metadata, effectively creating one trace for each. Then create one graph for each trace. I can't really tell you right now how to design your components to work with a future model where there is concurrency, since that model does not exist yet :).
