title: Target reference for each bar in Spotfire
body: <p>In Spotfire:
  Is it possible to show target value reference line for each bar in a bar chart.
  A way around that i am doing now is using combination chart. Refer screenshot.<img src="https://i.stack.imgur.com/IilMp.png" alt="enter image description here"></p>
  
  <p>The problem here is that now i can not define a color by property to color bars using rules.</p>
