Gnuplot: residuals of command line on output

Question

I am running ubuntu and in gnuplot, when I execute plot "<(awk '...' data.txt)" part of this command is drawn into the middle of the graph of data. The graph itself is correct, the problem is the text of the command that remains in the output. I could't find anything about other people experiencing residues like this. Does anyone have any idea where to problem might be or where to look for solution?

Code:

plot '<(awk "BEGIN{x=0} /^#previous/ {x++} /^#[^p]/ {x=0} /^[^m#]/ {if(x) print}" ./data.txt)' using 2:3

Source data:

#current

Dec 385 29  33  25

Output: enter image description here

How about adding the code used, the input file, and the graph showing the issue? I doubt you will get any help with the question in the current form. — Chris Seymour

Use notitle to fix this issue:

plot '< awk "/^#previous/{x=1}/^#[^p]/{x=0}/^[^m#]/&&x" data.txt' u 2:3 notitle

@Damell -- Alternatively, you could attach a meaningful title in the legend using title "something meaningful" if you wanted.
