[cosmetic] direction labels for the new error over time plots?

[moeller0]

The new error plots for occurrence different error types over a day are excellent!
Nitpick: on my version it is not clear which of the plots shows the up and which the down direction.

That's a good point (and in principle also affects the stats table, although it's much easier to guess what is what there).

I'll have to think about where to put the additional labels, so that they don't take too much space and work well for different viewport sizes.

I've also just stumbled over this and suggest you add Upstream and Downstream labels as headlines above the Connection parameters: and Error counters: tables.
