4.2 Diagnostic Functions: Formulas and Jython
The IDV provides methods to make computations using data in any IDV data source, and to display the results. You can use simple formulas or program code written in the Jython language.
4.2.0  Basics of IDV Formulas
How to Create and Use IDV Formulas
4.2.1  Jython Methods
How to Create and Use Jython-based Computations
4.2.2  Doing More With Formulas

Formulas can be used to do simple arithmetic such as the simple difference, or they can be used to call Jython procedures as in the previous excercise. They can also be used to call Java methods and nest Jython procedures. In this exercise, we will show how to create more complex formulas from the set of diagnostic functions in the IDV.
