Introduce a box with special symbols in Gnuplot

I want to have a gnuplot with a box on the right top corner like the one below. My difficulties are both:

  1. how to get \hat{Q} in a the legend?
  2. how to add a box containing the titles?

set term cairolatex eps standalone size 3in,3in
set output 'Q.tex'
set key box opaque samplen 0.5
plot for [i=1:4] sinc(x)**i title sprintf('\tiny${\hat{Q}=%d}$',i) lw 2

The standalone keyword wraps the output in minimal LaTeX commands so that you can run latex Q directly. Omit this if you want to produce a LaTeX fragment for including in a larger document.

I show how to construct a formatted title that includes a LaTeX font size. Note that the format uses single quotes rather than double quotes.

This example uses cairolatex eps because you specifically asked about an eps file. Normallay I would use cairolatex png or cairolatex pdf and process afterwards with pdflatex rather than plain latex.

If you want to include your figure into LaTeX, you should use the terminal cairolatex, then you can include LaTeX code in your plots:

plot "your.data" title '$\hat{Q}=10$'

Concerning your second question, have a look at the manual concerning set key.
