Steve Martin gave me the instructions below for a waterfall chart. He is summing columns essentially. In my data set, I need to have measures that are calculated FROM columns (so they are already aggregated).
Will it work the same way if I just remove the (SUM)?
// Now we have some fields, uses the index() function to plot our values against
// We need to use the Total() function to ensure all values in the set are brought through otherwise
// Tableau would break these values down to those of a non-existent set
Case Index()
When 1 Then Total(Sum(Sales))
When 2 Then Total(Sum(Profit))
When 3 Then Total(Sum([Unit Price]))
When 4 Then Total(Sum([Shipping Cost]))
End
