Legend - repeat of colours?

[User (Legacy)]

For some reason, the colours in the legend of my graph repeat. I can't seem

to find a reason in the code for this:

     ' These labels will appear in the tooltip

      for YCounter = 1 to benefit.rows

         benefit.row = YCounter

          If benefit.Value("BN-BEN-USED") = "0.00" then

          else

            Chart.Legend(YCounter-1) =  benefit.Value("BN-DESC")

          End If

       next
