Answer 1

Sometimes gnuplot cannot estimate the place needed for a string accurately enough. You already use the set key width command, try it with a negative width.

set key width -3

Result:

From the help set key documentation:

When using the TeX/LaTeX group of terminals or terminals in which formatting information is embedded in the string, gnuplot can only estimate the width of the string for key positioning.
