Using the Tag Explorer

Chart Configuration

The Chart List shows all charts for this profile. A chart can hold more than one variable plot and define some extra configuration parameters for all plots within. Chart grouping is important when you need to set different sampling rates for variables or when you need to set a different window size to accommodate more samples. Data for all charts are captured in real-time, even for charts that are not currently shown on screen.
