Hi @Celine1 ,
Do you know when a product type is being made? For example, are only certain products made during the phases that you show in your control chart? If so, you could make a column formula that is based on IF statements about whether it's Line 1 or Line 2, or Phase 1 or Phase 2 and assign the row value to a certain Product A, B, or C, and so on.
Or, if you have an anonymized data table to share, then it might be easier for someone to generate the analysis you're interested in and save it to the data table and post it back to the thread. Just a thought.
Hope this helps,
DS
