Multi-Layered Pie Charts
There are 3 multi-layered pie charts in the main window. Eye P.A.’s multi-layered pie charts continually divide each slice into more slices based on percentages. The size of each slice is proportionate to the total packets, bytes or time utilized.
The default ring order in Eye P.A:
2. Associated Clients
3. Frame Type
4. Subframe Type
Each element in the multi-layered pie chart can be clicked on, drilling down and breaking the data down into a new pie chart for easy troubleshooting.
To return to a parent layer, click the center of the pie chart, or the home icon in the top left of the window. The layer directly outside of the center is represented in the table. Double clicking on a row will change the pie charts
The bread crumbs represent the hierarchy of the current drill-down, helping you keep track of where you are in the file. Clicking the home icon will return to the default view with no drill-downs applied. The bread crumbs represent each click the user made to get to the current pie chart. At any level, the user can click on a bread crumb element to return to that multi-layered pie chart.
Hover (Inspector Tool)
When a user hovers over a slice in the pie chart, a tool tip box will appear, providing additional details like data rate, packet count and retry rate. This information is also displayed in the Associated Data Table.
ye P.A. displays all packet types captured in a .pcap file. It can be helpful to filter out certain types of packets like beacons, acknowledgements, or other non-essential frame types to bring out the packets
that matter the most.
To remove specific frame types from the multi-
layered pie charts, click “View” in the main menu at the top of the screen. Checking and unchecking frame types allows the user to selectively choose the which packets Eye P.A. will graph.
Note: Filtering packets will affect the data exported to WireShark. If “Beacons” are unchecked from the display filters, they will be excluded from the data you can export to WireShark.
The first two layers in the multi-layered pie chart are colored by the average data rate of the traffic. The shade of green is based on a sliding scale. The minimum average data rate captured is represented by light green, while the highest is represented by dark green, with shades in between.
Data frames carry the actual data passed down from higher layer protocols.

Control frames help with the delivery of the data frames. Control frames must be able to be heard by all stations; therefore, they must be transmitted at one of the basic rates. Control frames are also used to clear the channel, acquire the channel, and provide unicast frame acknowledgments.
