Colour scale
The Colour scale view is normally located on the left side of
the Echogram view.
The Colour scale view visualizes the mapping of echo
strength into one out of 12 colours, light blue for weak
signals and dark brown for strong signals. Basically, each
discrete colour represents a 3 dB range of echo signal
strength implying that the next colour is selected every
time the echo strength doubles. However, as the number of
colours can differ, and dedicated colour schemes can be
used, this is not necessarily correct
A high numeric TVG value displays weak echo signals
properly while the stronger signals saturate into dark
brown colour. A low numeric value displays strong echo
signals properly. Weak signals below the lower limit of the
colour scale are not displayed (the display background
colour is used).
If you place the cursor inside the view, a small yellow
label will appear to give you a detailed readout of certain
information. The
Tooltip dialogue defines which
information that will be shown.
If you click the right mouse button with the cursor
position within this view, a dedicated shortcut menu will
appear. If you click the middle button, the
Colour Scale
dialogue box opens.
