Graphs
The data collected in the Data collection databases can be displayed in the form of graphs (trend). This
provides an immediate view of the trend of the most important measurements or the possibility of comparing
the values of two different parts of the system in the same graph. To open the window of the graph, select
the
Display-Graph menu or click on the matching icon of the toolbar.
This type of graph is very similar to t hat of an oscilloscope. The time is indicated on the X (horizontal) axis.
The horizontal time scale is common to all the measurements displayed and is shown with indication of the
sampling date and time.
Using the specific
Select period button, you can select the display start and end period.
