title: Tableau Calculated fields with data blending
body: <p>I have 2 different data sources DS1 and DS2</p>
  
  <p>DS1 has week #( 1 to 49) , corresponding sales , ID </p>
  
  <p>DS 2 has week #(50 to 52) , corresponding sales , ID </p>
  
  <p>I did a data blending using ID as the relationship.</p>
  
  <p>Question : </p>
  
  <ol>
  <li><p>How do I draw a graph between week # and sales for the complete data (week 1 till week 52) </p></li>
  <li><p>Does calculated field provide functions to get this done ? </p></li>
  </ol>
  
  <p>Thanks in advance ! </p>
