Legend Select
The Select folder displays a list of all the charts
currently displayed on the screen.
From this folder you can choose the chart whose
legend information will be displayed in the Detail
folder, see Legend Detail.
The available charts are listed in Chart engine (C-
MAP or SevenCs) folders.
The set of charts displayed in the Select folder will
automatically update itself to match the cells most
recently displayed on the screen.
To view available charts click on the
+
button for
each chart database.
All the listed charts include a numerical value in
brackets. This value is the ratio of the current
display scale to the chart’s compilation scale, as shown on the
Detail
tab.
For example, if a chart has a compilation scale of 74500 and the current
range scale is 1:100,000, the ratio of these values is 74,500 divided by
100,000 equals x0.7, with the value rounded off to the nearest decimal
point.
Charts displayed in bold are currently under ownship's position, these
charts will match the charts ticked in the Charts button on the upper
toolbar. Charts not shown in bold are covering a portion of the display not
under own ship’s position.
Show Chart Coverage
The Select tab includes the option to display coverage of a selected chart
on the screen. To show chart coverage select a chart from the list and tick
the
Highlight Coverage of Selection
check box. The chart outline is
shown and the chart area filled in.
