title: How to set a line style as default for multiple plots in Gnuplot?
body: <p>I would like to create plot using gnuplot. The line width should be 3 in all plots. If I do it for one plot only this is done by:</p>
  
  <pre><code>set style line 1 linewidth 3
  </code></pre>
  
  <p>Is there any way how to do it globally as default?</p>
