Feature 1278, not all charts link to hosts

Feature 1278 was closed, but the only charts linking to anything are
on the dashboard.

I'm using the commit to 1278 as reference and expanding it to all
other charts. I think I have the fact charts done (working on what
I've tested on so far). I'm going to finish up with the statistic
page charts.

I was wondering if I should reopen 1278 and assign it to me since in
the description I said the goal was to have it apply to all charts …
or if you would prefer a new ticket created and assigned to myself.
