Graphing Time-Dependent Variables

We often need to provide graphical inputs into models. Limited data sets may be depicted conveniently in graphical form, because this allows the data to be interpolated—the gaps can be filled by a process which estimates the missing data. Here the method of creating graphical input to a time-based variable is explained and demonstrated.
     Powersim Studio GRAPH functions are explained. There are four GRAPH functions. Each of these defines inputs and possible outputs in a different way. Powersim Studio GRAPH functions are GRAPH, GRAPHCURVE, GRAPHLINAS and GRAPHSTEP. GRAPH is used as a representative example to explain and demonstrate how each might be used.
     The following is designed to explain how to build graphical relationships of variables which are time dependent .
