That's what #ChatGPT gave me when I asked for a #gnuplot script for a Parabola, and plot a vertical and horizontal line crossing the zero point.

I don't see a vertical line, and neither does it cross or touch the zero point.

The generated plot command:

plot f(x) with lines title "y = x^2 - 4x - 5", \
2 with lines title "Vertical Line" lc rgb "red" lw 2, \
-9 with lines title "Horizontal Line" lc rgb "blue" lw 2

Tevis, 4 months ago to cycling

I biked 4,042 km in 2023. 44.1% of that was for recreation; 55.9% was for utility (with 32.0% for my commute). Almost all of this was on my Raleigh Record Ace.

I spent $417.37 on #cycling, including building new bike stands for my office. That's $0.103/km, or $0.185/km if you only count utility cycling. Compare to about $0.40/km driving!

I used #ledgercli to track distances and expenses, and #gnuplot for the graph.

I think I'm gonna hack some nice #perl next year, haven't done that in a while. I also have a bunch of #R things I need to try, #D3 and some other libs and #gnuplot are waiting too and the rest will be lots of #SQL, a bunch of #go anyways and some #rust to be continued until it doesn't hurt anymore. ;) #programming

This may be my most truly cursed #cli ever for graphing #network performance?

This one has everything, a hand rolled artisanal #iperf3, some #json feature extraction, and a spot of #awk for fixing rounding errors, oh and of course, some red hot #gnuplot on #linux #terminal action.

Enjoy! hehe. 😆

./src/iperf3 -c testhost -p 22222 -J | jq '.intervals[].sum.bits_per_second' | awk '{$1=sprintf("%2.2f",$1)}1' | gnuplot -p -e "set term dumb ; plot '< cat -' with lines"

I have a couple of enviroment sensors attached to various #RaspberryPi boards dotted around the house.

I needed a way to collect the data, log it, analyse it, graph it and present it on a web page.

Written in #Python these scripts collect the #data, log it to a file, then use #gnuplot to create the graphs.

#Bash then pulls the graphs to an #Apache #webserver.
