y-axis labels.
Retransmitted packets and bad packets (packets with CRC or Header errors) are excluded from
throughput calculations.
Placing the mouse pointer on a data point shows a tooltip for that data point. The tooltip first line shows
the throughput, the throughput type (packet or payload), and the technology. Subsequent lines show the
bit count, the duration of the data point, the packet range of that duration (only packets of the applicable
technology from that packet range are used for the throughput calculation), and the number of the data
point (which is 0 for the first data point in each line).

The Throughput graph tool tips can be shown in the upper-left corner of your computer screen to provide

A discontinuity is when the timestamp going from one packet to the next either goes backward by any
amount or forward by more than 4.01 s. This value is used because the largest possible connection
interval in
Bluetooth
low energy is 4.0 s. A discontinuity is drawn as a vertical dashed line. A discontinuity
for a timestamp going backward is called a negative discontinuity and is shown in red. A discontinuity for a
timestamp going forward by more than 4.01 s is called a positive discontinuity and is shown in black. A
positive discontinuity is a cosmetic nicety to avoid lots of empty space. A negative discontinuity is an
error.
