Time charts in Content vs WIP by type

Hi:

I have a simulation of three product types to run through a queue. First, I want to draw two time charts. One is for the total (without considering the product type), another is for each product type. I discovered that the time chart for the total started from time zero, but the time chart for each product type started at the first event time of the incoming product. Can we make the chart for each product type start at zero so that I can compare the total and each product type?

Here is the flexsim program.

By default the "By Type" chart can't start from time zero, because it can't know which type values will be used in the model and thus can't create a "zero"-row for each of them.

You can change this adjusting the statistics collector that stores the data for the chart. Go to the "Advanved" tab in the chart's properties and "install" the components. This will make two statistics collector appear in the toolbox. Open the second one (the one that just has "Collector" in the name, not "Core").

Add a new "On Reset" event. Add the same label "delta" to the new event that the other events also use and set its value to 0. Finally, set the Row Values to be an array of all types that will appear in the model. This will create a row in the internal table for each of those types and thus make the chart start at time 0.
