Thanks @KaroMourad for implementing this!
As I already mentioned in #1971 though, this feature only really becomes useful if we can select min/max/first/last on a per-column-basis, as it was initially described in the feature request.

This is because some metrics are minimum-focused, such as loss, and others such as accuracy are maximum-focused, and for others still, such as step counters only the last value is important.
It would be really useful to be able to visualize all of this at the same time instead of alternating between four different views to gather this information.

@KaroMourad Do you think you could modify the implementation such that this becomes possible?
