title: User-defined scaling in gnuplot for y axis (equivalent to set logscale y)
body: <p>I have defined a function <code>f()</code> that I would like to use for scaling, in a similar way to logscale (but <code>f()</code> is not a logarithmic function). Is there a way to just do it automatically, like <code>set fscale y</code>?</p>
  
  <p>Otherwise I tried to plot the scaled function:</p>
  
  <pre><code>plot 'data' using 1:(f($2))
  </code></pre>
  
  <p>but then the scale on the y axis is obviously wrong. Can I use my function to rescale the y axis somehow?</p>
  
  <p>I would like to avoid having to set all the ticks and their labels manually (because I will use this script for a lot of different plots).</p>
