Displaying Data Graphs with a Trend Element

A Trend visualizes data that is used in the database of a trend recording. In contrast to the Trace element, the Trend element is particularly appropriate for long-term data recording.

The visualization of a trend encompasses the Trend element and the control elements. The three possible control elements 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 control elements 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.

You can display a trend visualization in the following variants (clients):

  • Target visualization

  • HMI: Communication takes place via a data sources manager

  • Integrated visualization
