Mixed disk graph results

[Rob Munsch <rmunsch (at) solutionsforprogress.com>]

Hello list,

I need to troubleshoot my disk usage graphs.  Running debian, i have 
both values and NaN on the same graph, when viewed under trends or Disk 
itself.  It's odd.

Frex, i'm looking now at a graph that has values for / and /boot, and 
lines are plotted; but the same graph is summarizing nan for /home and 
/shared.

All other tests are working fine.  It's only disk usage, across multiple 
hosts, that remains wonky.
