plot turtles vs energy

问题

Hello netlogo community

I have a simple model with 100 turtles and each one has a variable called energy. How can I draw a graph that plots for each turtle in the world his energy I mean: x-axis each turtle y-axis energy associated to the turtle

Sorry I think is an easy question but I can figure out how to do it. Ideally I would like an histogram like the following:

The NetLogo histogram command won't allow you to plot each value individually, but it's not too hard to code it yourself.

Supposing you have a model with the following code:

turtles-own [ energy ]
to setup
  clear-all
  create-turtles 100 [ set energy random 100 ]
  reset-ticks
end

You can add a plot with a pen that is defined like this:

(Don't forget to set the pen mode to "Bar"!)

To get a plot like this:

Note that this uses the new NetLogo 6.0 anonymous procedure syntax. In NetLogo <= 5.3.1, you'd use [ ask ? [ plot energy ] ] instead of [ [t] -> ask t [ plot energy ] ].

Also note that sort will sort your turtles by who number. Use sort-on if you prefer a different order.
