title: Plotting graph with gnuplot in Shell scripting
body: <p>I have to plot a graph using <code>gnuplot</code> with the help of shell script.
  I have written this code but its not working. I want to plot the graph in a html file so that I can see that graph in browser.</p>
  
  <pre><code> echo "set term canvas mousing size 500, 500
   set output "file_name.html"
   plot 'my_file.txt' with lines" | gnuplot
  </code></pre>
  
  <p>I have saved this file in .bash on the desktop.
  Now I wrote this in terminal but it didn't work </p>
  
  <pre><code>sh file_name.bash
  </code></pre>
  
  <p>Please someone help me out with this. I am totally stuck with this thing since yesterday. :-(</p>
