gnuplot set key at position and later move

Question

In gnuplot I'm trying to set the key at a specific position for a few plots, and then later I just want it in the bottom right corner of the screen. I tried:

set key at -5, 5
plot x
set key bottom right
replot

but the key doesn't move to the bottom right. How do I make gnuplot forget that I previously set a specific key location?

Answer 1

It only seems to be a problem if you use set key at

I got round it be adding set key default before the set key bottom right

set key at -5, 5
plot x
set key default
set key bottom right
replot
