* Overview of =daily-totals.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-totals.py
#+end_src

* Design/Trade-Off Notes and Decisions

1. The data used with this script is the most /symmetrical/, for lack of a
   better word, of all the CSV files I worked with. The number of rows and
   values in the ~date~ column (in both CSV files) are the same. So, there was
   no mapping issues along the x-axis -- like other scripts/charts.
2. I plotted the data on the chart with lines because that is the type of chart
   Nicola wants the main data/charts to be presented in.
   1. The aims of this script is a secondary pursuit. I did not think too much
      about the overall goal of it. The main aim of the project is/was to
      produce some line charts, so that is were my thinking is/was. This script
      is just a continuation of working in that vain. There is no reason for
      sticking with using a line chart with this script.

* What the Script Does

Essentially, it takes the total number of reading recorded for each day, for
each Light Meter, and plots them on the chart. For example, it will show on
~2021-06-15~ (16^th June 2021) Light Meter 1 recorded ~59336~ readings and Light
Meter 2 recorded ~117487~. It does this for every day and each line on the chart
represent one Light Meter.

Below is a sample of the data used by this script -- taken from
=../data/light-meter-1-daily-totals.csv=,

|               date | reading |
|--------------------+---------|
|         2021-06-13 |       6 |
|         2021-06-14 |   86729 |
|         2021-06-15 |       0 |
|         2021-06-16 |   59336 |
| MORE READINGS HERE |     ... |
|         2021-07-28 |   80334 |
|         2021-07-29 |   52618 |
|         2021-07-30 |   49776 |

The ~date~ column is used for the x-axis and the ~reading~ column is used for the
y-axis.
