Cardinal interpolation error
-Seems like for the big numbers, d3 is interpolating
data badly and it is creating loops in the chart.
So quick fix is to switch to linear interpolation
as default.
-Other interpolation can be set with settings.

Title:
Graph for cpu resource usage going backwards
Status in OpenStack Dashboard (Horizon):
Fix Released
Bug description:
Yesterday I could produce the attached image when I requested the
resource usage.
In the image you can see the line going left and even a loop.
In my opinion this is a bug. By looking at the data my feeling is
that there is an smoothing algorithm working at some point in order
(my guess) to look like a continuous measurement and it is overdoing.
