Based on some quick searching this doesn’t seem like it would be possible in the UI (v3.3.0) but looking for confirmation. I want to chart all values of say bios version but only for hosts where the bios vendor is x. The use case for something like this is identifying which hosts may need to have their bios, in this case, upgraded. From what I was seeing, you cannot search for facts in this manner but you can search for hosts. The alternative seems like it would be custom facts that combine vendor and version into a single value to be able to group based on vendor in this case.
