title: gnuplot: How to remove last tic without losing auto calculation of tic separation?
body: <p>In gnuplot, is it possible to autocalculate tic frequency in <code>set xtics</code> and still remove a specific tick?</p>
  
  <p>I want to draw a borderless arrow-through-origin coordinate system, this is still easy (showing only the x part to keep things simple):</p>
  
  <pre><code>unset border
  set xtics axis no mirror
  set arrow from minx,0 to maxx,0
  </code></pre>
  
  <p>With <code>minx</code> and <code>maxx</code> being two user-specified variables that are used to calculate all the sizes.</p>
  
  <p>The problem with the tics is now that the arrow has a tip with a tic, which is ugly. So I want to remove only the last tic, but still have the autocalculate <code>ticfreq</code> feature of gnuplot. By specifying the tics by hand (<code>&lt;start&gt;,&lt;increase&gt;,&lt;end&gt;</code>) one loses the autocalculate feature. And by removing the tic with <code>set xtics add ('' XMAX)</code> one only hides the tic label, but not the tic bar.</p>
  
  <p><strong>Is there any way to remove the last tic (bar and label) without giving up the auto calculation?</strong></p>
