title: Creating an extra slice in pie chart in crystal report
body: <p>I have a SQL which counts the number of rows. Say the result is 80.</p>
  
  <p>I would like to have a parameter that is user-input, to be the total. Lets say the user enters 100.</p>
  
  <p>How would I use the two numbers, 80 and 100, to create a pie chart that shows the data takes up 80% of the total?</p>
  
  <p>I cannot find a way to add custom slice in a pie chart in Crystal Report, is it even possible?</p>
  
  <p>Thanks!</p>
