    Vertical Parameter/Reference/Drop Line not in version 8?

    Heather Bute

      Hello,

       

      Does anyone know how to add a vertical reference line, or drop line, or parameter to a dual axis graph in a version of Tableau prior to version 8?

       

      I am displaying the values of supply and demand on my Y axis and the year and month of that qty on my X axis.  I basically need to draw a line in the sand between what is History data and Forecast data. I saw another question about this on here but the response was done version 8 and I can't open it because my company is not realeasing version 8 until August.  Does anyone know how to do this in a prior version?
