title: Why data does not refresh the same way between OSIsoft PI Processbook & PI DataLink?
body: <p>I'm checking for one PI tag in Datalink &amp; in Processbook.
  In Datalink I see Compressed Data interrupted few hours ago, in Processbook for the same PI tag I see continuous trend, which looks normal.</p>
  <p>I thought the both tools should show the results for the same tags.</p>
  <p>Why are they giving different results?</p>
