Having taken out the database stuff, there seems to be no single obvious

My point is, do people want to actually read values off this sort of plot,
or just get a qualitative feel for what's happening and where?

Again, I just wonder whether people do actually use the ticks marks in
practice, or whether the borders are sufficient to give your eye something
to hang on to.
