Data Logging / Graphs

[Rob F]

I hope it works for everyone. If not I'll add a high low scale.

The graphs for the ec and tds will change for every value, 200, 201, 202 etc...

I've got 12 graphs made now, you can view 84 days on the display for all of them. 

• water temp
  
• light temp
  
• extra temp 1
  
• extra temp 2
  
• ph
  
• orp
  
• dissolved oxygen
  
• saturation
  
• conductivity
  
• tds
  
• salinity
  
• specific gravity
  

They should work well, there all based off the RTC not using millis. It stores a reading every 8 minutes 35 seconds and then a few seconds before midnight. If the controller is off the graph continues in the correct spot when turning it back on. For example if the controller was off at 7pm and back on at 9pm the graph would continue at 9pm. Between 7pm and 9pm would be blank on the graph because no data was captured for that time.

Just finishing up the labeling and trying to figure out the other parameter ranges.
