I’m developing a data source plugin for a “database” which returns everything as
string. So I’m challenged to convert fields to the “right” type.
I’m wondering, what the best approach is here.
I’m parsing as
time when the column is named “time”.
Otherwise, I attempt to parse every field as an
intVal, err := strconv.Atoi(*stringVal)
However, Grafana still does not recognize it as numeric and complains “No numeric fields found”. Only when I add (in the user interface) a transformation of “Convert field type” to Numeric, I have beautiful charts.
What’s expected here for my plugin to return?
Thanks for our help
