Hi A.
Could you provide a screenshot of your Graph Builder contents so our helpful JMP experts can better assist you?
(you can rename variables, pixelate or blur the sensitive areas to anonymize, if needed)
Like what Jim Nelson said, the Overlay Grouping Variable drop zone (fig. 1, label # 1) will help you see the trend you want - by factors (based on your setup).
However, you mentioned that:
"...with treatment as Y grouping and date as X grouping." (fig. 1, label # 2).
If you put the date in the Group X drop zone (fig. 1, label # 2), you won't be able to see a trend or use the Line & Overlay option (fig. 3).
Using the Group X drop zone, the mini graphs will be separated and will behave independently of each other - like the scatterplot matrix or R Studio's ggplot facet.
To see the trend (connected lines across dates), you need to put the dates in the X drop zone (fig. 2).
* This is based on my limited knowledge of JMP 12. Please correct if needed.
Hope this helps.
