Here are the L\u003cvideo of the\ntalk|https://www.youtube.com/watch?v=Qvb_uNkFGNQ\u0026t=12830s\u003e and the\nL\u003c\"slides\"|https://github.com/dkogan/talk-feedgnuplot-vnlog/blob/master/feedgnuplot-vnlog.org\u003e.\n\n=head1 NAME\n\nfeedgnuplot - General purpose pipe-oriented plotting tool\n\n=head1 SYNOPSIS\n\nSimple plotting of piped data:\n\n $ seq 5 | awk \u0027{print 2*$1, $1*$1}\u0027\n 2 1\n 4 4\n 6 9\n 8 16\n 10 25\n\n $ seq 5 | awk \u0027{print 2*$1, $1*$1}\u0027 |\n   feedgnuplot               \\\n     --lines                 \\\n     --points                \\\n     --title \"Test plot\"     \\\n     --y2 1                  \\\n     --unset key             \\\n     --unset grid\n\n=for html \u003cp\u003e\u003cimg src=\"documentation-header-plot.svg\"\u003e\n\nSimple real-time plotting example: plot how much data is received on the wlan0\nnetwork interface in bytes/second. This plot updates at 1Hz, and shows the last\n10sec of history. The plot shown here is the final state of a sample run\n\n $ while true; do\n     sleep 1;\n     cat /proc/net/dev;\n   done \\\n   | gawk \u0027/wlan0/ {if(b) {print $2-b; N++; fflush()} b=$2} N==15 {exit}\u0027 \\\n   | feedgnuplot            \\\n       --lines              \\\n       --title \"wlan0 throughput\" \\\n       --stream             \\\n       --xlen 10            \\\n       --ylabel \u0027Bytes/sec\u0027 \\\n       --xlabel seconds     \\\n       --unset key          \\\n       --unset grid\n\n=for html \u003cp\u003e\u003cimg src=\"documentation-header-network-throughput-plot.svg\"\u003e\n\n=head1 DESCRIPTION\n\nThis is a flexible, command-line-oriented frontend to Gnuplot. It creates plots\nfrom data coming in on STDIN or given in a filename passed on the commandline.\nVarious data representations are supported, as is hardcopy output and streaming\ndisplay of live data. For a tutorial and a gallery please see the guide at\nL\u003chttps://github.com/dkogan/feedgnuplot/blob/master/guide/guide.org\u003e\n\nA simple example:\n\n $ seq 5 | awk \u0027{print 2*$1, $1*$1}\u0027 | feedgnuplot\n\nYou should see a plot with t",
