I find myself extremely confused about how `Placed` works with plot legends. I want my legend to partially hang over one edge of the plot. But

```
Plot[Sin[x], {x, -1, 1}, PlotLegends -> Placed[{"Sine"}, {.975, .75}]]

```

produces

which is no good because the label gets cut off. As soon as I increase the first coordinate up to 1, it works okay, but space is really tight in my desired application and I can't afford to waste all that white space under the curve.

I've tried using the optional second pair of coordinates in `Placed`, but I can't figure out how they work - When I hold the first pair fixed and change the values of the second pair, they seem to be moving my legend in the *opposite* direction as I would expect (e.g. changing the coordinates to `{{1, .75}, {2, 0}}` moves the legend to the *left*), and I also have no idea what's setting the scaling of the second pair of coordinates.

I found the question [Legend placement explanation](https://mathematica.stackexchange.com/questions/63333/legend-placement-explanation), but I can't follow the example because it has so much extraneous crap in it and the answers don't go into enough detail. Not much detail in the documentation for `Placed` either.

Would this maybe be a job for `Show`, `Inset`, or `Overlay`? I'm not really sure about their relative advantages.

Finally, I noticed that using `Placed` changes the legend's text from left-aligned to centered. How do I change it back?

**Edit:** Regarding my last question, the easiest way to change the text alignment of the legend is to change `{"Sine"}` to `LineLegend[{"Sine"}, LabelStyle -> {TextAlignment -> Left}]`.
