Graph View

The data that appears in the graph view is somewhat dependent on your hardware and device driver.

• The green bars indicate signal strength. The higher the bar, the better the signal.
• The red bars, if available, indicate noise level. The higher the bar, the higher the noise.
• The gap between the green and red bars is equivalent to signal to noise ratio.
• A purple bar indicates loss of signal, possibly temporary.

Some configurations, such as ORiNOCO and Prism cards, provide accurate measurements of both signal and noise data, which can be displayed in full with units of dBm.

Other configurations, and in particular any card using the NDIS 5.1 device access method, do not provide noise information, and may provide RSSI instead of signal information. In these cases, NetStumbler may omit the noise display and only display RSSI.

The graph view will automatically scroll to keep up with new data if you are viewing the rightmost part of it.
