When the Engineering Chart opens, it displays a default data set according to the data range specified in the point configuration. This means that the graph will always initialise showing raw data or averages; however, there are other options.

Under the options menu, we can choose one of the following options.

Additionally, for options other than Raw, we can choose the resolution.

For example, if we choose Average and Weekly then click the refresh button, we will get weekly average plot.

Note that the header has changed to reflect the aggregation.
