If you want more than one trace in a given graph, you can specify
-t more than once.
+ -F Add a fio bandwidth log graph. You need to run fio --bandwidth-log

-l Sets a label in the graph for a trace file. The labels are added in
the same order the trace files are added.
current second with seconds from the past. Longer numbers here
give you flatter graphs.
+ -P add per-process tags to the IO. Each process responsible for

+
-O add a single graph to the output. By default all the graphs
are included, but with -O you get only the graphs you ask for.
-O may be used more than once.

Choices for -O and -N are:
