Cleaning up graphs on trends page

I've been playing around with my graphs on the trends page by tweaking
the analysis.cfg file.  It seems now, that I have lines stuck on my
graphs that no longer exist.  I'm also seeing that I have 3 different
"Network Ports" graphs. How do I clean these up so only real graphs are
displaying?
