The element displays the curve of variable values as a trend diagram. The trend diagram is suitable for representing a long-term data curve because the data is read from a trend recording and hence from a database. Moreover, you can run the “Trend” element together with the “Date Range Picker”, “Legend”, and “Time Range Picker” operating elements so that the user can navigate conveniently in the diagram.
You can programmatically delete the recorded trend curve at runtime. The recording starts again from the time of deletion.

The “Trend” visualization element cannot be inserted into a visualization in the POU pool.
