title: Removing the path name of the data when plotting in gnuplot
body: <p>I am relatively new to gnuplot and I am trying to plot some data and save it to a png file for a report. I am running gnuplot from a java-program using exec("gnuplot") but whenever I try to read data from a file and plot it, the plot contains the full path name of the datafile and prints it over part of my plot.</p>
  
  <p>This makes the plot look rather ugly and unfit for my report. Is there a command or something that I can use to remove the path name or do I have to use Photoshop to render it away manually after generating a .png?</p>
