title: How to set axis units in gnuplot
body: <p>I'm trying to generate some schematic figures using gnuplot. My x scale is of angstrom and the y scale if of mV. Currently, I have the x scale goes like:</p>
  
  <pre><code>0 1e-9 2e-9 3e-9 etc.
  </code></pre>
  
  <p>And my y scale goes like</p>
  
  <pre><code>-0.07 -0.06 -0.05 etc.
  </code></pre>
  
  <p>And I want them to be</p>
  
  <pre><code>0 10 20 30 etc.
  -70.0 -60.0 -50.0 etc.
  </code></pre>
  
  <p>respectively. 
  Is there a way to do this from within the gnuplot (apart from setting the xrange an yrange parameters and multiplying the values by the appropriate amounts)?</p>
