Stella is a little continuous time system simulation product. Like so many simulation packages it asks for exact values for all coefficients and plots spidery thin lines representing the behavior of the model. I would like to put together a prototype demonstration, using Mathematica 3.0, that would like to demonstrate a user interface where coefficients had, for example, a normal distribution and where graphs of the behavior over time were plotted as a fuzzy band. Perhaps this could be done using dots, more closely spaced where the probability was high and less closely spaced where the probability was low. I have been experimenting, trying to craft up a plotting function that would convey the uncertainty in a value over time but not by covering the graph with confidence bars. Anyone have any examples or ideas that I might learn from? many thanks psu04033@odin.cc.pdx.edu
