Stored changes to measured values and error codes are displayed by the change bar or control bar below a graph. This change bar marks all changes that have been made to a time series and orders them sequentially in time. In this way, users can record changes made to a time series "at a glance".

Information accessed by the change bar is comma-separated and structured in the following way, so that the display is standardised accordingly:

▪User, transaction name, comment, execution time.

In the graphical display, AquisNet automatically enumerates the changes, ordered by time stamp and time series.

Detailed information on the changes of a transaction can be found in the transaction detail displays (see above).
