title: Setting the key (legend) coordinates doesn't work?
body: <p>I would like to move the key to some location in the middle of the plot, so I followed the tutorials and have the following script:</p>
  
  <pre><code>set terminal postscript eps enhanced color
  set title "Risk of the loan"
  
  set output 'simulation.eps'
  set xlabel 'Initial loan value'
  #set key height 24
  set key 8,0.7
  
  plot 'simulation.txt' using 1:2 title 'Discounted loan value' with lines lw 3,\
       'simulation.txt' using 1:3 title 'VaR' with lines lw 3,\
       'simulation.txt' using 1:4 title 'CVaR' with lines lw 3,\
       'simulation.txt' using 1:5 title 'Probability of default' with lines lw 3
  </code></pre>
  
  <p>However, when I run it I get:</p>
  
  <pre><code>ga1009@ga1009-dell:~$ gnuplot simulation.p
  
  set key 8,0.7
          ^
  "simulation.p", line 7: unknown key option
  </code></pre>
  
  <p>What am I doing wrong?</p>
