title: Charts don't plot if using values below 1 second
body: <p>I am extremely new to Grafana, I am using Grafana v4.1.1, influxdb 1.2 and have a range of charts showing my data :) </p>
  
  <p>If I change my __interval from 1s to 100ms, nothing plots on the charts.  I can hover over and it has values at ever one second though?</p>

  <p>I have also added the table view and cannot get milliseconds to display (tried ss.sss, ms etc).  I know the data has them as viewing the date as a string displays as below</p>
