Update objects in financial analysis

[ FlexSim 25.0.3 ]

Hello, I need help modifying the objects considered in the financial analysis graph, which are trucks (Camiones) in my real model. I've attached an example with the problem to be solved.

Basically, in my model, I use a parameter (Camiones_XL) to define the number of active trucks to be considered during the simulation, and I have a trigger On Model Reset that updates the members of the active truck group ("Group_Camiones_XL") by taking resources from the "Group_Camiones_XL_MAX" group, which contains the maximum number of trucks. (I do this because I need a model which could be used without a license)

My problem is that the objects in the financial analysis graph aren't updated based on the active trucks group. Unfortunately, the "sampler" doesn't run for groups, and I'm not sure if it's recommended to destroy and create new nodes through the model tree.

Could someone explain me how to solve this?

Thanks in advance.

You can often times find useful information by 'exploring' GUI elements.

It takes a bit of experience, but you can find out what code is executed when certain GUI elements are pressed and then just use that code yourself.

In this case, we can find that there is a "function_s"-call to add objects to the chart. The "focus" here is the chart object.

At to remove objects, the code also just deletes the link-nodes from the chart's tree.

In both cases the code also calls "onchangeobjectset" on the class object. I don't know if that is important to do but probably can't hurt to do as well.

So in summary:

Object chart = Model.find("Tools/Statistics/Financial Analysis");
Object te = ...;

// Adding
function_s(chart, "addMember", te);
function_s(classobject(chart), "onchangeobjectset", chart);

// Removing
treenode objects = getvarnode(chart, "objects");
for(int i = 1; i <= objects.subnodes.length; i++) {
    if(ownerobject(objects.subnodes.value) == te) {
        objects.subnodes.destroy();
        break;
    }
}

This is a new world for me, but I think it's time to jump in and keep moving forward 😉 I've modified the trigger with the fuctions you mentioned and it works! Thank you so much for your help.

Do you know how to do the same but for a distance traveled chart, for example? I tried to use the same logic by exploring the structure and using the commands there, but it isn't working.

The travel distance chart stores the attached objects in a group. Adding task executers to that group will make them appear in the chart after the next model reset.

Group objects = Model.find("Tools/ChartTemplates/Travel Distance>stats/primaryGroup/primaryGroup"); objects.addMember(Model.find("Operator1"));

To track transient objects (TE's that are created and destroyed during the model run) you can use a custom Statistics Collector instead.
