Example
In this epidemic model, the trait ‘Had disease’ was created to keep track of all of the agents who had contracted the disease at some point. These agents were tracked on the line graph in purple. The ‘or’ block was used in the if statement so that agents with the color red or the color blue could be specified.
Note: Because the ‘or’ block has a round peg and the ‘count within’ block used for the line graph only takes inputs with a square peg, it is impossible to simply count agents with ‘color red or blue’ for the line graph. This is why the trait ‘Had disease?’ was created. Now the line graph ‘contracted disease’ series counts agents within 200 steps with ‘Had disease?’ = 1.
