Each taxon page for a plant species (such as this page for Triteleia crocea ) shows a graph of Plant Phenology associated with observations for each month. Users can associate multiple phenologies (Budding / Flowering / Fruiting) with an observation because some plants will have multiple phases present at the same time.
Phenology stats show up fine on the graph, but the display algorithm makes a wrong assumption for the “No Annotations” figure for each month. Specifically, the algorithm appears to assume that the “No Annotations” figure can be calculated by subtracting the sum of all three phenology counts from the total observation count. In the case shown, iNat has calculated that 4 total obs - (4 flowering + 4 budding + 1 fruiting) = -5 obs with “No Annotation”.
I’m hoping that it is quick fix to have the algorithm generate the correct number by making an additional call to find the count of records for this taxon and month that have no associated annotations. If you can fix this, that will better allow users to discover and check observations that are missing annotations.
