@bagder Maybe something like this... Based of https://curl.se/docs/releases.csv
Not double checked (yet) the awk, date scripts to generate the input for gnu plot. And the gnu plot script is neither presentable yet. But it seems to work.
@bagder there is now a gist with the gnuplot script at https://gist.github.com/recollir/8f3bcd6c91a482dc9a5b13b7fc823799
And an open issue for it at https://github.com/curl/stats/issues/28
Feel free to use it however you want.
@bagder I guess this is UTC and that the night commits then happened for people in a more suitable time time zone. At least I hope.
I somehow saw that one could draw a “background” in gnuplot. I fill it with the gray squares. Then I overlay the data. Which has been put into four buckets for the values. Each bucket got a color assigned to it.
