Echogram and Range
The Echogram and Range view consists of an Echogram field
to the left and a Range field to the right. These are separated by
the vertical range axis. The Echogram field contains
information about the acoustical values, while the Range field is
used for specifying the range used in the Echogram field. The
settings in the
Colour Scale
is used to present the information.
When you place the cursor in the Echogram field, you can use
the mouse wheel to modify the gain setting, and hence the
display colour sensitivity. Each click of the wheel corresponds
to a 1 dB change. The same gain setting is available from the
Colour Scale
dialogue box.
