title: Tableau: Multiple columns in a filter
body: <p>I have three numeric fields named A,B,C and wants them in a single filter in tableau and based on the one selected in that filter a line chart will be shown. For e.g. in filter <strong>Stages</strong> B column is selected and line chart of B is shown. Had it been column A selected then line chart of A would be displayed .</p>
  <p>Pardon my way of asking question by showing a image. I just picked up learning tableau and not getting this trick any where.</p>
