Public bug reported:

The vCPUs usage chart is confusing because it can end up with values
like "Used 5 of 4".

(see e.g. https://launchpadlibrarian.net/155236888/Nova_bug_1202965.png
which was posted on bug 1202965)

This may be improved in Nova as part of bug 1202965 but I think if it is
possible we should try to make the meaning clearer in Horizon. Chatting
with a Nova developer and based on the discussion on that other bug as
well, the actual meaning is: "This hypervisor has 4 cores and is running
VMs with a total of 5 vCPUs." - which is a bit too long for the chart
legend itself.

I'd like to suggest adding a star (*) after the small chart legend and
putting this full sentence as a legend below the chart series. It may
not be the best UI but hopefully it will help with reducing confusion -
I'm including the UX tag on this so UX folks can hopefully add their
input as well.
