title: Gnuplot different colors
body: <p>I'm trying to color a plot and a fit in gnuplot in different colors, but it doesn't work:</p>
  
  <pre><code>set ylabel "s in m"
  set xlabel "t in s"
  unset key
  set style line 1 lt 2 lc rgb "red" lw 3
  set style line 2 lt 2 lc rgb "orange" lw 2
  plot "-" with lines ls1
  0 0
  1 4.2
  2 7.9
  3 11.7
  4 16.3
  fit "-" with lines ls2
  0 0
  1 4.2
  2 7.9
  3 11.7
  4 16.3
  </code></pre>
  
  <p>Does anybody have an idea what I am doing wrong?</p>
