A trend (also called history) is a table of records generally associated with a real time point. Each record follows a unique format detailed below. The type of the value column corresponds to a type of associable real time point.
There are usually 4 fields associated with a trend row
| Timestamp | Trend Flags | Status | Value |
|---|---|---|---|
ISO 8601 format | Mark a record {Start}, {End}, {Modified}... | Status of the point at the time of registration | Boolean, Double, Integer (enum) or String |
Not all real-time points have an associated trend. Trends can be queried through the API over a given period.
