Control Point Statistics using Tracked Variable

In attached model, I want to track the number of AGVs passing over a particular control point. The model was built using following posts as a reference

https://answers.flexsim.com/questions/30755/collecting-statistics-on-agvs-and-agv-networks.html and

https://answers.flexsim.com/questions/80701/graph-multiple-data-of-a-tracked-variable-in-one-c.html

I created a tracked variable "Content" whose value is incremented by a Wait for Event Activity on entry of an AGV at CP8. A statistics collector is built that will give current, minimum, maximum and average value of this variable

The difficulty lies in determining the type of chart that will plot this variable. What is it that I got wrong?

Hi @Amit Kulkarni,

Thanks for doing the leg work and attaching a model for this question. I looked at the model you attached, and I think one of the things that was maybe throwing off your graph was that the Row Add Value & Event Value fields were both "data.NewValue" and they should be "data.newValue". This will solve the errors you're getting in the statistics collector (see pictures below).

Before:

After:

Once this is set up, you can use a basic Time Plot graph and set the data source to the "Content_LineGraph" Statistics Collector. That should give you what you need to watch the value of the Content variable change with time. Note that I didn't see the Content variable decrease, which is what I expected it would do based on your description. Hopefully this is working correctly.

Let me know if you have any questions about this.

A simple follow up question, is there a way to use a table plot to see numeric values of the variable Content?

I found it! I had that option minimized in the toolbar.
