A couple of simple scripts that plot lines of C code in src/ versus time using gnuplot.
Copy count.sh to a clean labwc repo checked out at master.
Run
./count.sh $(head -n 1 /path/to/data.txt | awk '{ print $1 }') >> tmp.txt
Copy the contents of tmp.txt to the top of data.txt
Run ./plot.sh and then view graph.png
