Here is a typical wizard graphics configuration screen:
The next screen allows you to set the scale and grid parameters for the slots, as well as the slot
type. MagLog produces an automatic display layout based on your configuration and the
following rules:
•
Magnetic field is always displayed in the wrapped mode. This means that when the graph
reaches the slot’s border, it reappears from other side of the slot.
•
Signal strength can be displayed as in wrapped mode or in fixed mode. In fixed mode
slot’s borders have fixed values; if value to be plotted is out of this range, the curve
simply disappear from the screen.
•
Depth also can be plotted in either mode.
•
If there are depth and altimeter sensors, MagLog makes a “flying fish” plot. This includes
plotting of sum of depth+altitude to show bottom profile and depth plotting in the same
slot to show the fish’s actual vertical position in the water column. This kind of plot has a
fixed range with the positive axis pointing down (in landscape mode) or left (in portrait
mode).
In the dialog box below, the user can set ranges and scales for all the above slots, as well as total
slot’s duration in seconds (speed of trace control).
