title: How can I get rid of the ticmarks on the x2 & y2 axes of a gnuplot?
body: <p>Here is a picture of the problem I am facing: <a href="https://i.stack.imgur.com/dMQbp.png" rel="nofollow noreferrer">Gnuplot</a></p>
  
  <p>Additional unlabelled tics appear in my gnuplot on the x2&amp;y2 axis. This is how I have defined the plot:</p>
  
  <pre><code>set grid lt -1 lw 0.709
  set border 3 lt -1 lw 0.992
  set size ratio 0.71
  set view 60, 30, 1, 1 
  set ticslevel 0.5
  
  #fonts
  set title font "IsonormD,16"
  #set xtics font "IsonormD,16"
  set ytics font "IsonormD,16"
  set key font "IsonormD,16"
  set xlabel font "IsonormD,16"
  set ylabel font "IsonormD,16"
  </code></pre>
  
  <p>after this come only labels and the plot command. Sorry it seems I can't add a picture but would be thankful for advice.</p>
