After selecting a connected PNF supporting ONF-TR-532 and a physical
interface, the application collects the received and centralized stored
-performance values for this interface. The data gets displayed as a line
-chart to visualize the data in a given time period and a corresponding
-table. If the table gets filtered, the chart updates itself.
+performance values for this interface.
+
+The values are visualized using two views: a line chart and a table,
+with the chart always shown first. To switch between them, toggle
+buttons can be used. The chart view offers a filter to quickly limit the
+shown values. To keep both views in sync, the filters of the chart and
+the table are connected. If one view is filtered, the other one gets
+updated in the background.
