gnuplot - removing line title

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. 

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"

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?

If you had more untitled lines than titled lines, it's more convenient to disable titles by default using set key noautotitle:

set key noautotitle

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 with lines lc rgb "black"

To accomplish this you should use the notitle tag.

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 with lines lc rgb "black" notitle

or a more general example;

plot 'File.dat' using 1:2 notitle

an alternative that is equivalent to notitle is to set the title to a zero character string;

plot 'File.dat' using 1:2 title ""

If you are not above a bit of trickery:

Just omitting the last "Without CloneScale" title will remove both title and line from the legend. Setting the last title to a space will show the line and (seemingly) nothing before it in the legend:

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 ' ' with lines lc rgb "black"
