Displaying Data Graphs with a Trend Element
A Trend visualizes data which is used in the database of a trend recording. In contrast to the Trace element, the Trend element is particularly suitable for long-term data sampling.
The visualization of a trend encompasses the Trend element and the controls. The three possible controls can be seen in the illustration.
Legend ①: Outputs the trend variables with values.
Time Range Picker ②: Provides buttons for selecting predefined time ranges.
Date Range Picker ③: Encompasses controls for navigation and zooming in the historical and current data on basis of the set date range.
A cursor is optionally available that enables the reading of a value at a certain time.

HMI: Communication is made via a data source manager.
