title: GNUPLOT cannot zoom in
body: <p>I am having an issue where I am unable to zoom in on my GNUPLOT. I created a bash script that records various resource information, and displays this information via the following command.</p>
  
  <pre><code>gnuplot -e persist "set title 'Resource monitor' ; set timefmt '%y/%m/%d-%H:%M:%S' ; set xdata time ; set xlabel 'TIME' ; set ylabel 'PERCENT' set yrange [0:101]" -e "plot '${cpuResFile}' using 1:2 title 'CPU' smooth Bezier, '${memResFile}' using 1:2 title 'MEM' smooth Bezier" &amp;
  </code></pre>
  
  <p>The graph is viewable and displays my information I want, I just cannot figure out how to allow it to zoom in and out. I read that it has something to do with the X11 window no longer being set or that I need to set it via the command line, I just cannot figure out exactly how to, or if this is even the reason. Hopefully there are a couple GNUPLOT experts that can assist me. :)</p>
  
  <p>Thank you.</p>
