A trend graph in the context of ibaPDA is a display of a certain combination of signal charts and curves. Similar to a recorder, trend graphs are used to show live measured data.

Each trend graph view can basically consist of an arbitrary number of curves. The signal curves can be zoomed in and the scales changed.

The pause button can be used to stop a current trend graph, for example, in order to consider the measured values. The data storage continues in the background.

The default configuration shows a trend graph view without a graph, X or Y axes. After you configured the signals in the I/O manager, they are immediately available for display. For better clarity, you may open several views, which can be arranged in different windows side by side or in tabs.

In addition to the normal trend graph, there are also trend graphs for displaying data from the ibaHD server ("HD-trend graph") and existing measurement files ("offline trend graph"). The basic operation of trend graphs is the same for all types.
