You can use the split ratio to adjust the sizes of a split pane.
This option is available only on the split zoom, the split bottom
lock, and the split 50/200 pane. The GB40 must be displaying one
of these

7.23 Echosounder: A-Scope - show/hide
The A-Scope appears in the right side of your Echosounder as a
column of multi-colored, horizontal lines that are constantly
moving. It shows a real-time image of each sonar pulse so that
you can optimize the gain and the gain threshold levels for the
current sonar frequency.
The A-Scope shows:
• strong echoes as long horizontal lines
• weak echoes as short horizontal lines
The advanced A-Scope also shows:
• a static thin red vertical line showing the maximum sonar
amplitude. You can't change this. Any echoes that exceed this
maximum are always shown in red
• a white (or black) thin vertical line showing the selected
minimum amplitude, which controls the range of colors
displayed. You can change this using the gain threshold.
Any echoes that don't reach this minimum are shown in the
background color of the current palette
• a color bar at the top of the A-scope, showing the colors
associated with each amplitude. You can change the width of
the colors using the gain.
