title: Crystal Reports: ? Possible to show Full Set in one chart, and subsets in separate charts?
body: <p>In Crystal Reports, is there a way to get both full set charting and subset charting, in the report headers?</p>
  
  <p>I'm working on a report from an erstwhile co-worker and I'm still trying to make things "better".</p>
  
  <p>While I haven't found the solution to accruing time 
  ( see <a href="https://stackoverflow.com/questions/5995723/accruing-over-time-non-overlapping-technique">Accruing over time (non-overlapping) - technique?</a> )<br>
  I'll press on with how to use the resulting data once I retrieve it.</p>
  
  <p>The report is a Global Availability report for network technologies, and part of the report is graphic:</p>
  
  <ul>
  <li>Chart availability for different
  network types for last "n" months'
  time. </li>
  <li>Charts availability for each region
  (for each network type for "n"
  months' time).</li>
  </ul>
  
  <p>She (co-worker) had a global chart, but for each region, she did a separate sub-report containing just the chart for that region.  The query isn't optimal, and using the sub-reports, the query is repeated each time.</p>
  
  <p>If there a way to use a single data-set in one report for all five charts, forcing the four regional charts to display only that region's data?</p>
  
  <p>Additional info:
  The charts are all Bar charts, design is 
  y-axis:  calculated availability 
  x-axis:  Group by network type (Switches, Trunks, "Network)
       sub group by month</p>
