I personally have never understood the keywords associated with key placement.

The one combination I do know how to use,  I remember by thinking of it as
    "place the bottom/top left/right corner of the key at position x,y"
You can use any coordinate for the x,y position so it works to place the
key inside or outside of the plot.

In your case would be something like

         set key bottom right at graph 1.0, 1.0

I.e, place the bottom right corner of the key just above the top right corner of the plot.
