I’m building an Agent Based Modeling system like NetLogo. Their plotting support is mainly line/point charts and histograms that grow with every step of the model. The line charts may show two or more parameters but most commonly only one.
A concrete example would be a “boids” flocking model, with the chart showing the “coherence” of the flock via their heading: 0 means no coherence (random headings) while 1 would mean each boid had the same heading. At every step of the model, the new coherence point would be added.
Another would be predator/prey with two lines: one for wolfs, the other for rabbits. Evolving quickly with new points for each step.
So matching the NetLogo plotting ability gets us an A.
