title: How to plot two datasets from two different columns from one file in Gnuplot?
body: <p>I have one file with two columns containing A/D-samples from two sources. All values are within the range 0-1023 (inclusive) and the sources are not dependant on each other. That is, they are completely different.</p>
  
  <p>Sample excerpt from the datafile:</p>
  
  <pre><code>188   631
  196   593
  203   594
  210   593
  218   595
  225   593
  233   594
  240   602
  247   593
  255   594
  262   593
  269   594
  277   593
  284   594
  </code></pre>
  
  <p>All the values in the first column belongs to A/D-source #1, while all the values in the second column belongs to A/D-source #2.</p>
  
  <p>Now, what I what to do is to get two lines/plots of the respective A/D-source, in the same plot. Since this is my first shot at Gnuplot, I have a hard time to get it right since it seems that no matter what I do Gnuplot interprets the datafile lines as (X, Y) rather than (Y1, Y2) which is what I want. Doing a plain <code>plot 'datafile'</code> will simply bomb all values in a scattered mess.</p>
  
  <p>How do I tell Gnuplot that this particular file contains two datasets, one in each column?</p>
