title: Grafana graph to display call response time
body: <p>I have been playing with Grafana for a while, and got stuck with the following issue.
  I need to produce a chart that displays the round trip time for some REST calls my application is doing.
  I am using Dropwizard metrics and starting a PausableTimer when I fire the call, and stop it when the expected response comes back. From Grafana, then, I can see the data source I need but when I build the graph, I am forced to apply some statistical calculation on my data (stddev, mean, max, min, etc.) whereas all I need is to chart the numbers from the series.</p>
  
  <p>Below is a screenshot of the config part I am referring to:

  <p>The dropdown contains a number of transformations to apply to the priginal data, and I cannot find a way to tell Grafana that I wans to display the data the way it is.</p>
  
  <p>I am not really sure how to do this, had anyone had this issue before -- and solved it?</p>
  
  <p>Thanks in advance.</p>
