title: gnuplot - removing line title
body: <p>I tried searching, but I couldn't find the solution for this particular condition. In my plot , I am comparing two traces. I am using a line graph and both traces are plotted with different colors. </p>
  
  <pre><code>plot "delay_try1.dat" using 1:2 title 'With CloneScale' with lines, \
       "normal_2.dat" using 1:2 title "Without CloneScale" with lines lc rgb "black", \
       "normal2.dat" using 1:2 title 'Without CloneScale' with lines lc rgb "black"
  </code></pre>
  
  <p>Using this plot command, I get 3 titles in legends and 2 are repeating ones. I just want 2 titles to appear and remove the repeating one. Is it possible to do this?</p>
