Fish histogram
The fish histogram shows, in graph form, signal strength distribution for the school(s)
of fish marked with an estimate mark on the horizontal displays. The histogram display
for each of those displays will be different since the calculation method is different.
This data appears only when an estimate mark is active. When two estimate marks
are active, histograms are displayed one on top of the other as below.
The horizontal axis shows signal strength in 16 colors, and the vertical axis shows the
concentration of a school of fish inside the fish estimate mark. For the fish estimate
mark inscribed on the horizontal display the graph shows the average movement in
five scans, to increase accuracy.
Note:
The histogram display is redrawn five transmissions after a fish estimate mark
is erased and another mark of the same number is entered soon after.
