For example

Expression 1:

    1. Label = Exp1

    2. Definition = 2    (use your calculation)

Expression 2:

    1. Label = Exp2

    2. Definition = 3    (use your calculation)

Expression 3:

    1. Label = Exp3

    2. Definition = [Exp1]*[Exp2]

This mean that, for expression you can take label from expression 1 & 2 for any calculation

In a  chart you can use the column number to represent the expression for example if you want to use an expression that is present in column 2 you can write as follows

if(column2= null,' ', ' ')

This will work as long as subsequent expressions are not promoted in place of column 1 and/or column 2
