title: How do I create a stacked graph of HTTP codes in Kibana?
body: <p>I'm sending HTTP logs into Kibana, and the response code (200, 401, 500, etc) are correctly parsed out of them as a field. I'd like a time-series chart with the count of each code shown as bars stacked on top of each other in each interval, in different colors. This should help see if there are suddenly more 500 errors, for example.</p>
  
  <p>I'm having a hard time figuring out how to create such a chart in Kibana. Is this possible?</p>
