Defining a New Variable

1. Select Variables -> New Variable in the User-Defined Variables & Filtering window.

1. The Variable Editor appears.

   You can define new variables in terms of existing variables. You define the new variable by writing an equation in the edit box at the top of the Variable Editor dialog.

2. Define a new variable called POWER that is defined as the product of two existing variables, tq and n, by entering POWER=tq*n, as seen in the example following. You can also double-click variable names and operators to add them, which can be useful to avoid typing mistakes in variable names, which must be exact including case.
3. Click OK to add this variable to the current data set.

   

This new variable appears in the top list (variable expression) of the User-Defined Variables & Filtering window.

POWER also appears in the Data Information pane, along with the original variables, and its definition is included in the description field (to the right of the units column; you might have to scroll or resize to see it).
