title: is it possible to set the position of a label relative to the key in gnuplot?
body: <p>The nature of my plot is such that absolute labels don't really work; I can't restrict the range in y, so wondered if there was a way to either include my label text inside the key or have it placed relative to the key (i.e. below)</p>
  
  <pre><code>set term png enhanced size 1024,768
  set title "{/=15 1D My title}\n - by me"
  set xlabel "x"
  set ylabel "y"
  set label "V_0 = 10\n E = 1" #this is the bit I want to reposition
  set out 'trial.png'
  set xrange [-2.5:2.5]
  set arrow from -2,-2000 to -2,2000 nohead size screen 0.025,30,45 ls 1
  set arrow from 2,-2000 to 2,2000 nohead size screen 0.025,30,45 ls 1
  plot 'data.dat'
  </code></pre>
  
  <p>PS: also, is there a better way to get my vertical lines at x = -2 and x = 2? The arrows solution is again not ideal since my y range is often greater or smaller than 2000.</p>
