title: How to control non-existent data items in SSRS chart at runtime?
body: <p>we have created a SSRS report with a big chart that have multiple entries in values </p>
  
  <p>its a line chart so it is having many lines ( as number of entries in the value section)</p>
  
  <p>we need to control the lines that shows in the chart from our ASPX page</p>
  
  <p>its ok to create a chart with one line graph in it
  and its ok to create a chart with multiple line graphs in it</p>
  
  <p>but the thing is the user should be able to select he want one line , 2 lines , 3 lines in the graph</p>
  
  <p>so lets say the chart shows ( expenses, revenue , profit) as line graphs in one chart</p>
  
  <p>if the user selects to see only revenue it should only show the line graph in the chart
  but if the user selects expenses &amp; revenue  so both line graphs should be shown in the same chart ( showing where they are intersecting if they are)</p>
  
  <p>how to control this can i controle this by parameters and how ?</p>
