System Dynamics Pitfalls and Pointers
Making Graphs Easier to Read
Sometimes graphs of changes over time have values that are
the same, or nearly the same, for part of a
given simulation, as other graphs. This can result printouts being
superimposed on each other, with the consequence that a graph
of particular interest could be obscured for at least part
of a simulation. A simple way of avoiding this is
to add a conveniently chosen constant to the output parameter.
Note that multiplying the output parameter, rather than adding a
constant value to it, can produce a misleading plot.
The following
is designed to explain how to clearly depict graphical printouts
