I am very open to allow GPM data within the app. Another user suggested a station specific popup showing its detail. I think for backwards compatibility we can put this data in another file on the SD and pull it when available like the watering level log is handled. This way they can be polled separately.
I ripped out the old graphing library as it gave me many issues and made the timeline default. I am looking for a new graphing library and plan to have a candidate soon to replace it and reincorporate graphs that are responsive. Once that is completed we can easily plot flow data as well.
