body: <p>I have a view that has the below fields:</p>

  <p>In Power BI I need to display a card that shows a 4 week average as a percentage.</p>
  
  <p>So the data above shows the total amount of emails sent per day, what I need to figure out is :
  week 1 we sent 1000, week 2 we sent 1500 etc</p>
  
  <p>So the percentage increase week on week is 50%.</p>
  
  <p>I need to be able to calculate this increase/decrease as a percentage and show it on a card.</p>
  
  <p>I have tried all of the quick measures and nothing seems to work, I have tried another example from the bi community here: <a href="https://community.powerbi.com/t5/Desktop/How-to-calculate-average-growth/td-p/289403" rel="nofollow noreferrer">https://community.powerbi.com/t5/Desktop/How-to-calculate-average-growth/td-p/289403</a></p>
  
  <p>and that did not work.</p>
  
  <p>Any help would be greatly appreciated.</p>
