title: Zero results in Google Analytics Reporting API V4?
body: <p>Using the v4 API for PHP, I have noticed that zero results do not appear as rows in the results.</p>
  
  <p>In using the ga:avgSessionDuration metric and ga:date dimension for a period of 1 week, days that have a 0 for the average session duration do not return in the data, so I do not have a whole week to chart.</p>
  
  <p>According to the docs, v3 will return 0 lines, and in the Query Explorer, the zero values show up since they are using the v3 API. But it seems that v4 does not, at least not without additional configuration, unless I missed something.</p>
  
  <p>Has anyone else come across this, and is there a solution?</p>
