title: How to use HighCharts to plot aggregate hourly event rates?
body: <p>I'm persisting every application error I get to our DB, and exposing it as an endpoint that gives a time series of errors:</p>
  
  <pre><code>[[1354445413000,1],[1354445502000,1],[1354445522000,1]]
  </code></pre>
  
  <p>Format is <code>(Timestamp, 1)</code>, (second value is always 1), the series contain a value per error I have in the system.</p>
  
  <p>What's the easiest way to get HighCharts to show a periodic aggregate chart with drilldown - something that shows N error events per day, and can be drilled down to an hourly or zoomed out to a weekly resolution? (note that zooming changes the actual data being displayed, not just the resolution).</p>
  
  <p>Drill-down &amp; zoom out are not essential, my first focus is just getting HighCharts to aggregate the data for me.</p>
