    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.
