However I think there is a bug in the graphing. The ambient temperature graph is not plottet correctly at the grid/scale. Have a look at this example where beer and ambient are about identical. Notice ambient show 19ªC (a decimal here would be nice) and beer is 19.4ºC.
Details show that posted values to brewers friend are correct.
If you're asking the question, then most likely that did break . Apologies again, I did not test thoroughly enough on my end. We'll revisit this once more in the future, let me know if the feature has anymore significant graphing issues in it's current state and we'll re-prioritize accordingly.
Revisiting this issue. The original issue was resolved back in March but it broke "Auto Scale Fermentation Chart Y axis scale." - Is that issue still open in your ticket/issue-tracker? To me it still looks unresolved?
Thanks for the following @steinmb, I've added this thread and some more examples to the issue. It seems to me that it's just a matter of the ambient data not saving, but will followup here when I have more details.
