title: Showing String in Grafana Graph
body: <p>I am play with Grafana, reading some metrics from a Rails app, just for test propose. </p>
  
  <p>My data is something like that:</p>
  
  <pre><code> {:endpoint=&gt;"POST_ItemsController#create", :duration=&gt;2938.779, :view_runtime=&gt;2901.051}
  </code></pre>
  
  <p>But I don't know how (if is possible) show the endpoint name in the Graph, my query:</p>
  
  <pre><code>SELECT "duration", "endpoint" FROM "endpoint_stats" WHERE $timeFilter
  </code></pre>
  
  <p>And the result:</p>
