gray-only Kaplan-Meier plots have less functionality than the original ones

The colored ones used to work just fine and now it doesn't.

Whatever the solution, we need one that allows users to compare: (1) the how survival in one group to all others (could be done with extra curves in small multiples) (2) the survival of a subset of two or more curves to each other within the subset (requires color or labels in header brick or detail view - but ideally in the header brick because the detail view kicks out columns ...)

All this ideally without walking the mouse around, this is very tedious.

As I said on skype I'm extremely reluctant to re-introduce colors (for aesthetic reasons, but also for practical ones: we use color for many things already and it would be better to not use colors twice).

Showing all lines in all multiples is definitely an option for me.

I don't fully understand (2). However, I think if you can't recognize a curve by it's shape and magnitude it's probably a very small difference.

Regarding shapes: the problem with the shape of survival curves is that they are often quite similar (by design).

Here is an example for (2). I want to compare the selected, the hovered and the curve between them (2nd from top). I can't tell which of the many gray curves represents the one between the hovered and the selected.
