statistics on individual path agents - anylogic

Question

I am simulating a medical stay and would like to calculate for each patient generated the cost of their stay. I have created a parameter that is updated each time the patient receives care. However, to plot it, I created a histogram data with a cyclic event that updates the values every hour with the following code:
this.CostperPatient.reset();
for (Patient patients: this.patients)
{
this.CostperPatient.add(patients.cost);
}
However, the chart it produces does not give an indication of individual patients, it makes a percentage.
Is there any way to output a graph with the cost for each individual patient?
Thank U

While I am not sure what you are trying to show, it seems that in your case, you shouldn't be using a histogram, instead you should probably use a bar chart where each bar is for a patient. To do so, drag to your model in the main environment a bar chart element and call it chart. To dynamically add bars to this element, you need to use something called "data items". For now, remove all data items from the chart by clicking on the X in the properties.
Then, go to the Agent window, so your patients' agent window. Add a variable. Set it as follows:
Then, in the agent's properties, in the on startup field write the following:
Finally, add a cyclic event in the agent's window with the following code:
patientCost.setValue(cost);
Where cost in the above, refers to your initial variable called cost in the question. That should do it.
