I have now added the ability to log various readings for a ferment.
At this stage users can log:
Gravity (this can be specific gravity or Plato)
Graphs for entered readings are available in the Graphs section of the ferment log page
Readings can be entered in the Readings section of the ferment lgo details page
Once you are logged in, a small reading entry widget is available on the front page for quick entry of values
Graphs are available for review in the Graphs section of the ferment log details page. Graphs only display when you enter details so if you never enter any pH readings, the pH graph will not be visibile.
