Make it easier to select displayed data range

[michaelwoerister]

It would be very handy to have clickable shortcuts for displaying

• the last week
• the last month
• the last 3 months

in the "graph" view.

Also, some kind of calendar widget for selecting dates would be nice (though less important).

Not sure if this still makes sense.

Just in case people are not aware: I have found that one can drag a rectangle over the graphs to zoom into that region. So one in theory can get the presentation being requested here; but it might still be nice to have more convenient access, since manually clicking and dragging is both onerous and fragile.
