title: how to plot percentage on grafana?
body: <p>I have success and failure metrics as follows:</p>
  
  <pre><code>A.B.p1.success
  A.B.p3.success
  A.B.p4.success
  ...
  
  A.B.p1.failure
  A.B.p2.failure
  A.B.p4.failure
  ...
  </code></pre>
  
  <p>I have in total ~30 persons, and I want to show the each person's success rate as calculated by: </p>
  
  <pre><code>alias(asPercent(A.B.p1.success,sumSeries(A.B.p1.success,A.B.p1.failure)), 'p1')
  </code></pre>
  
  <p>The problem I have:</p>
  
  <p>1) If I hard-code all the persons in each row, it exceeds the max row Grafana allowed, andd I want to plot them on the same graph</p>
  
  <p>2) If there a way I can do it by a Grafana function?</p>
  
  <p>Thanks in advance!</p>
