4-14 Description
In the Graph 2D, the horizontal axis represents Frequency, the vertical axis
is the Time and the colour is the Level.
The signal amplitude is represented in a scale of arbitrary colours, usually
the darker the lower and the brighter the higher, like in thermography.
The Color Scale referenced to levels and units, is indicated on the left bar on
the screen.

A Marker function is also available, to allow investigating a specific signal.
Fig.4-23 2D Marker
In the box indicated by the arrow it is shown the Frequency of the Marker
(5.00 Hz in the example above), the level (0.226 mT) and the time of the
trace since the waterfall window was started. You can place a marker
anywhere on the spectrum display with a mouse click.
