Graph Term

Overview

A Graph Term is a special type of Term in which values are determined by a function from the current time (or from the value of another term) to real values. Graph Terms allow you to incorporate real-world data into your models. You can import data in CSV form, use that data to build a function, then use the function in models you build in Numerus.

You create a Graph Term by selecting the Graph Function option on the Term properties panel, and then clicking on Edit Graph Function to specify the function.

Graph Function Edit Panel

A new Graph Function will open a panel with a function mapping all values to 0, as shown in Figure 1. Figure 2 shows an annotated Graph Term which is discussed below. (Click to enlarge)
