title: how to change gnuplot's graph size
body: <p>I am trying to plot a graph with increased font size in gnuplot. A typical example is:</p>
  
  <pre><code>p sin(x) w l lw 5
  set border lw 4
  set tics font "Halvetica Bold,20"
  </code></pre>
  
  <p>So, I am trying to have:</p>
  
  <ol>
  <li>adjust plot size without changing the canvas size to accommodate x/y label and tics</li>
  <li>to adjust space between tics and label</li>
  </ol>
  
  <p>How can I achieve this?
  Kindly help.</p>
