title: How t have the RDLC pie chart show ranges instead of individual values
body: <p>I have some data coming from a custom dataset that look like the following example</p>
  
  <p>Person Age</p>
  
  <p>P1      20</p>
  
  <p>P2      21</p>
  
  <p>P3      30</p>
  
  <p>P4      31</p>
  
  <p>P5      40</p>
  
  <p>And I want to develop a pie showing the age distribution against the age.</p>
  
  <p>The point is that I want this Age to be shown in ranges. (20-29, 30-39, etc for example
  So we have:
  Slice with total number =2 (P1 + P2) as age is 20-29 (one at 20 and another at 21)</p>
  
  <p>Slice with total number =3 (P3 + P4) as age is 30-39 (one at 30 and another at 31)</p>
  
  <p>Slice with total number =1 (P5) as age is 40 (one at 40).</p>
  
  <p>How can i customize the pie chart to aggregate values by ranges that I can define?</p>
