The topN chart shows top talker information for a selected port, agent, zone, site or subnet trended over an hour. For example the chart below shows statistics for 10.36.160.2 port 5:

InMon Corp:Head Office:Building 2:10.36.160.0:10.36.160.2:5

Instructions:  Clicking on elements of the location path above the table jumps to a status table for that part of the network. Click on bars in the chart to identify contributors to traffic in that interval. Click on the last bar to restore the default behavior of displaying contributors to most recent interval. To change to a TopN view, click on the option button in the bottom left of the chart and select a chart type.  Use the option button on the bottom right to scale the chart by frames or by bytes (utilization). The intervals and interval size options control the number of bars displayed and the duration of each bar respectively. The arrow buttons (<< and >>) allow the chart to be scrolled forward and backward through time.

Note: The gray part of the each bar represents "other" traffic, i.e. traffic not belonging to one of the top five connections.
