hi all It's a couple of weeks I am using Mason on my Mac to learn to use it. I have the sensation that with Mason it is impossible to create graphs at the starting of simulation. For example, the original heatbugs model written in Swarm contains a plot of "unhappines" of the mean of all unhappinesses values of heatbugs. In Mason implementation there's not such graph, but it is possible to plot the happiness of one heatbug. Is that true or not? All examples are of models in which there are a raster with various agents in it. I have not found a model of only graphs. Regards.
