title: Gnuplot no lines drawn
body: <p>My problem is that gnuplot does not draw any lines. That applies to <code>linespoints</code> and <code>lines</code>. Here is my script:</p>
  
  <pre><code>set terminal postscript 
  set output "bla.eps"                                                         
  set datafile separator "\t"     
  set autoscale                                                                  
  set grid
  set yrange [0:12]                                                              
  unset log
  unset label                                                                    
  set xtic auto   
  set xtics font "Times-Roman, 10"                                               
  set ytic auto 
  
  plot "times.dat" using 1:($4/1000):xtic(1) title "naive" with linespoints lc rgb "red" pt 7 ps 1.3   
  </code></pre>
  
  <p>My .dat file has as the first column some data that I want to intepret as a text, while other columns are numbers. I just don't see any lines printed on the screen. Points are just fine. Even if I make the first column a number column, or I use <code>lines</code>, it doesn't matter, there is no line. Any clue?</p>
