In case anyone is interested, I created a new larrd def for hobbitgraph.cfg that uses the name "cached" instead of "real" in the trend chart. I did it because I found "real" and "actual" to be too confusing, since the words mean roughly the same thing in day to day use, but not on a Linux system! :)
Just thought I'd throw it out there in case someone else wants to use it.
