title: How to plot 10th power range in gnuplot or xmgrace?
body: <p>I am using the following data set:</p>
  
  <pre><code>x = 10, 20, 50, 100;
  y = 1.2e-5, 3.5e-8, 6.8e-14, 2.5e-20;
  </code></pre>
  
  <p>If I plot x:y in gnuplot or xmgrace, the y points in the plots are indistinguishable (particularly the last three ones). </p>
  
  <p>Is there is any trick to customize the y axis so that smooth and distinguishable points are obtained?</p>
  
  <p>Thanks.</p>
