title: Using XY Graph as Control
body: <p>What I want to do is using a XY Graph as an user input control that gives me x and y values at the same time. I was able to switch the XY Graph from indicator to control in the block diagram but there is no effect at runtime. </p>
  
  <p>No data is coming out from the XY Graph.</p>
  
  <p>To get the data from the XY Graph I use a "Index Array" Block and an "Unbundle By Name" block to unbundle the first elment to X and Y coords.</p>
