Plotting attribute of a non-consecutive agentset

How can I plot an attribute of an agentset in netlogo, each with a different pen. Consider there are other types of agents also, and the who numbers of the agentset to be plotted are not all consecutive to distribution/creation at start.

I take it that your question is really, "how can I associate each agent in an agentset with a pen?" Let's call the agentset myset.

  1. If the agentset is static (no agents created or dying) during the simulation, then you can introduce global mylst and set it once to list of agents: set mylst [self] of myset. You can then associate the pens with members of the list anyway you want. (E.g., you could also make a list of pens so that an agent's index in mylst and its pen's index in mypens is the same.)

  2. You could use table and map each pen name to an agent. (I probably like this solution best.)

  3. If these agents constitute a breed, you could give the breed a pen attribute that you set to its pen name. (The only reason I dislike this solution is that it meddles with the attributes of the agent purely for GUI purposes, which I try to avoid.)

EDIT:

Since you are creating and destroying your agents, but you want each to control its own pen, you have a somewhat weird situation that could lead to a lot of bookkeeping. I'm going to suggest solution 3: add a pen attribute to your agents. Now each time you create an agent, include as part of its initialization the following:

set pen (word "pen" who)
set-current-plot "myplot"
create-temporary-plot-pen pen
plot attribute

Here "myplot" is the name of the plot you are using for this, and attribute is the name of the attribute your are plotting. Then each tick you can have each of these agents

set-current-plot "myplot"
set-current-plot-pen pen
plot attribute

If you want to distinguish agents by pen color, you will have to do a little extra work. (See the scale-color command for clues.)
