points per line reaches 300, the number of data points per line is halved to 150 and the duration per data
point is doubled. The duration per data point thus progresses from 0.1 s to 0.2 s to 0.4 s to 0.8 s and so on.
4.3.4.11 Throughput Graph Y-axis labels
The y-axis labels show the throughput in bits per second. From left-to-right the labels are for 802.11,
Bluetooth low energy, and Classic Bluetooth . The duration of each data point must be taken into account
for the y-axis label’s value to be meaningful. For example, if a data point has a duration of 0.1 s and a bit
count of 100, it will have a throughput of 1,000 bits/s, and the y-axis labels will be consistent with this.

4.3.4.12 Excluded packets
Retransmitted packets and bad packets (packets with CRC or Header errors) are excluded from
throughput calculations.
4.3.4.13 Tooltips
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
an unobstructed view. Refer to
Relocating Tool Tips .
