Pontifications

  • one krazy idea would be to plot number of support questions by hour and day by operating system and send an alert if they vary say by more than plus/minus 20% than the previous day<--- i did this on a daily basis for Thunderbird back in 2010 for email providers
  • Don't know how I ended up at Plot labels from ends of lines on stackoverflow but from it I learned that the R package directlabels allows you label end of lines in ggplot2
  • And group_by() allows you to group by multiple variables e.g. group_by(os, week) allows you to group by operating system and week which is how you plot by OS and week
  • This allows me to make last week's FF62 operating system plot more legible by labelling the OS lines individually.
