You can move a measurement value by using drag & drop to the trend area and the graph will be displayed for the designated time window. Different values can be moved in one trend control and can be compared directly.
The major feature is that the measurement values can be moved on the time axis. Therefore one and the same value can be viewed for today, yesterday and the last week. In this way you can perform time-shifted cause analysis and impact analysis. The reaction after parametrization will take effect in process after some time.
