title: Gnuplot multiplot how to keep the plot of equal size after removing tics and axis labels?
body: <p>I would be very happy if someone could help me in my attempt to produce a decent plot</p>
  
  <p>I want to obtain something like this may be with less margins between the single plots
  <img src="https://i.stack.imgur.com/ZCUaL.jpg" alt="as_should be"></p>
  
  <p>so I first plot this 
  <img src="https://i.stack.imgur.com/wXNWA.jpg" alt="enter image description here">
  and I manually edited it with gimp to remove unnecessary tics and labels</p>
  
  <p>I tried to unset labels and tics in my gnuplot script but all I got is this disgusting stuff

  <p>this is the gnuplot script that produced that horrible plot I do not understand how I can fix the dimensions of the single windows so that they will be of equal size</p>
