* 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 [[file:../README.org][README]] for more
information on setting the repository up.

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

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

* 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 [[file:./dailies-overlayed.org][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
   [[file:../daily-breakdowns.py][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.
