BasicIo graphs:
Io graphs is a very useful tool. The basic Wireshark Io graph displays the overall traffic in the packet capture file, usually in the unit of per second (number of packets or bytes ). By default, the x-axis interval is 1 second, And the y-axis is the number of packets at each time interval. To view the number of bits or bytes per second, click "unit" and select the desired content from the "Y axis" drop-down list. This is a ba
