Overview of daily-comparisons.py Script

I have assumed you have ran ./separator.sh and ./totalilator.sh, created a virtual-environment (venv) (python3 -m venv venv) and installed the dependencies (via pip -r install requirements.txt). See the project's README for more information on setting the repository up.

  cd <PATH TO RITHERDON-CHARTS>
  # Activate the virtual-environment if you haven't...
  source venv/bin/activate

  # Run the script...
  python daily-comparisons.py

Design/Trade-Off Notes and Decisions

1. Each Light Meter has different timestamps which are difficult to map onto each other. So, I have assigned each reading an Id. number instead. This means the time element of these charts is reduced, for lack of a better word.

   1. Both Light Meters took a different amount of readings from each other throughout the course of the exhibition. This has added to the difficulty of mapping the x-axis range between the two Light Meters.
   2. The charts paint the general pattern of behaviour for a given day and not an exact retelling of the days events – to the nearest minute/second.
   3. I have gone into more detail in dailies-overlayed.org if you want more information on this design constraint. It is the exact same problem I had to overcome and the same tactic I used there (replace timestamps with Id. numbers).
2. These charts are not the main aim of this project. I started working on this script after completing the main task – which I did with the daily-breakdowns.py script. Accuracy was not a major goal. I thought it was interesting to see the general patterns of behaviour between the two Light Meters across the same day.

What the Script Does

This script produces charts which compares the readings collected by both Light Meter readings on the same day. As a general observation, Light Meter 1 tended to record less readings (for various reasons) than Light Meter 2. So, you will find the readings for Light Meter 1 stop a lot sooner than Light Meter 2 when viewing the charts.
