Data Logging / Graphs

[Rob F]

Just to wrap this up, here's how it ended. In a few updates I'll be adding logs for the equipment as well.

• Data is logged every 8 minutes 35 seconds for each of the sensors, if the sensor isn't plugged in no logs are created.
  
• Each day a new log file is created and named in this format "wt-4-11-2016.txt  The "wt" at the beginning is water temperature, that prefix changes for each of the sensors. 
  
• Each sensors log files are saved in their own folder.
  
• You can view data daily, weekly, bi-weekly and monthly. When using the bi-weekly view it goes back to 1977 lol...
  
• You can turn on an optional vertical grid, the horizontal grid is always on
  
• The daily view is instant, weekly view takes a second to load, bi-weekly 2 seconds and monthly just under 5 seconds.
  
• You can change from a bar graph to a line graph.
  
• Each of the views remembers the days you were last viewing. If you looked at January on the ph graph and then went to view the orp graph by the month you would also see January instead of something else, useful for comparing.
  
• Times show in 12hr or 24hr format
  
• Temperatures show in C or F.
