Watch the Calculation as It Happens

In order to achieve flexibility, sensitivity, and robustness, I plot departures of the variables of interest from specified reference values. A bar projecting to the right of the middle of the panel indicates a value larger than the reference value. A bar projecting to the left indicates a smaller value. The length of the bar is proportional to [Pg.61]

The parameters of the display are established in GRAFINIT, and the number of variables to watch is specified by numplot. There must be a corresponding number of reference values in the plotz array, sensitivity values in the plots array, and labels in the plotl array. As a convenient start, I set plotz equal to the initial values and plots equal to the initial [Pg.61]

Subroutine PLOTTER actually plots the relative values of the elements of an array called ploty. In this subroutine it is necessary only to set the values of ploty according to the labels specified in GRAFINIT. It is not necessary to plot all of the dependent variables, y, and it is possible to plot derived quantities like the concentrations of dissolved carbon species, by simply specifying what is wanted in GRAFINIT and PLOTTER. The cores of these two subroutines, GRINC and PLTC, do not need to be modified for different simulations. [Pg.62]
