Equation Selector
The Equation Selector tool helps you choose a function to work with. Functions are used to manipulate your data, similar to how equations and functions work in Microsoft Excel.
For a step-by-step example of using functions, see the About Equations article.
If you don't already have a function in your "select" then clicking on the Equation button will open the Equation Selector.
The Equation is accessible from the Tag Editor.

Use the equation selector window to choose a function. You can filter which ones show by setting a category.
When you click on a function, it will give you more information on that function.
Once you have selected a function, click Ok to continue to the Equation Editor.
