arbtt-graphs

[Joachim Breitner]

Hi, especially Waldir,

inspired by your link to
http://blog.stephenwolfram.com/2012/03/the-personal-analytics-of-my-life/ I saw if I could create such a graph from my arbtt data, and after a quick proptype I got the attached image (cropped, to preserve at least a bit of my privacy). Every vertical line is one day, every pixel is 6 minutes. You can see the daylight savings time switch, my usual lunch times, and the afternoon break. Red is active, grey is computer just on, black is computer off.

In the full image I also recognize holidays, changes of my daily
schedule, different timezones.

It is definitely interesting, but I’m not yet satisfied with the visual
quality. Maybe antialiasing of some kind helps; increasing the
resolution will probably not help, given that I sample only minutely.

In a final version, you’d probably want to be able to select tags that
should be colored differently, or automatically color pixels by tag
category (e.g. program used).

I also need to find a library that takes care of the graph axes and
labels for me.

Comments welcome,
Joachim
