I have category pages, with a list of products inside each of them.
The category pages contain details on tests which have been conducted for each of the products, with some categories having up to 50 products, and some category pages only having 1/2 products.
The products undergo the same tests regardless of the category they fall under; and the outcomes and results are displayed across 3 different charts.
Given that every category shows the same 3 chart types — if a category doesn't have any results yet for 1 of the charts, would it be best to hide that chart? Or display an empty state explaining that there have been no results yet for that particular type of test?
