title: Custom Dimensions and Date Ranges with Google Analytics Reporting API v4
body: <p>My report request includes <code>ga:nthDay</code> and <code>ga:dimension3</code> dimensions for metrics in a date range, but it isn't returning a row of data for each Day Index.</p>
  
  <p>I suspect this is because my custom dimension isn't matching for each day in the range — but why don't they all return a <code>0</code> value for each metric?</p>
  
  <p>For example, since I'm using <code>ga:nthDay</code>, I'll get rows with a Day Index of 0000 and 0002 — but no 0001. These rows will sometimes display <code>0</code> value for the metrics, but other times the rows just aren't returned at all.</p>
  
  <p>How do I handle the missing days?</p>
