title: gnuplot - multiple lines with different x ranges
body: <p>I am using gnuplot to try and plot several lines but each have different x ranges. I am running the following script:</p>
  
  <pre><code># gnuplot script for 'omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat'
  plot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:2 with lines title '1'
  replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:3 with lines title '2'
  replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:4 with lines title '3'
  replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:5 with lines title '4'
  replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:6 with lines title '5'
  replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:7 with lines title '6'
  replot "omarConf2EvONLY-vs-everyone-gta-lag-lpas-omarConf1-random-tag-tpas.dat" using 1:8 with lines title '7'
  
  set terminal png size 800,600
  set output "omar_vs_everyone-EVONLY.png"
  replot
  </code></pre>
  
  <p>and the .dat file is just a file with columns such as:</p>
  
  <pre><code>1 0.5 0.5 0.1
  2 0.6 1.3 0.8
  3 0.7 0.32
  4 0.7 0.35
  5 1.3 4.32
  6 1.67
  </code></pre>
  
  <p>notice that the columns have different lengths as each line has different x ranges.</p>
  
  <p>The problem I have is that it plots funny as shown below:
