This script places all the daily reading for a given Light Meter and overlays
them on top of each other on the chart. Because each file (for each day)
have different combinations of date/timestamps, the charts has to switch to
using plain integers for the x-axis. This means you can't glean much data from a
time/date spective but the charts for both Light Meters do help relay the
amount of activity which happened in them.
I didn't mean to create this script.
It takes the individual daily readings for a Light Meter and places each 'daily
readings' next to each other, on the same graph. This is essentially stitching
the full log of reading back together but with gaps between the individual
charts. The gaps are formed, I think -- I haven't checked -- because the
'missing data' (when the factory was closed or no welding was happening) is
being treated as such. I'm assuming it's because I've passed each 'daily line'
as separate lines so Bokeh has no reason to join them together.
This script makes a HTML chart for both Light Meters. And, the charts are slow
and not very nice to deal with. I've only kept the script and the charts it
produces because the charts look interesting as images and I want to see what
Nic thinks. She might find them useful from an artistic perspective.
The script now processes all the daily files for both Light Meters. Each day,
for each Light Meter, has their own chart (HTML) made as the output of the
script.
