Hi. I want to use abm\_exploration to display data that requires access to both agents and model, something like this:

```julia
function demo()
	model = initialise_model()
	params = Dict(
		:reaction_norm => 0:0.01:1,
	)
	plotkwargs = (
		ac=(ag->ag.exploit),
		as=30,
		adata = [
			((agent->(agent.genetic_radius < model.food_radius)), count),
		],
		alabels=["Genetic success"],
	)
	playground, = abmexploration( model; agent_step!, params, plotkwargs...)

	playground
end

```

The problem seems to be that `model` is not available to adata - I had hoped that `model.food_radius` would simply insert its numberical value into the call, but that is not the case. I thought of evaulating `model.food_radius` before the call to abmexploration, but I couldn’t find out how to do it. Can someone please tell me what I’m missing?

Thanks.

Hi, the model and the agents are available to the `mdata` though. So you can create a custom function that access the model field you want, and its agents with e.g. looping over `allagents(model)`.

CU!

Got it - thanks very much! 😄
