If there is no chart data available for the geographical region being viewed,
all component fields show No Chart Available.
Chart Usage / Scale
The chart usage scale displays the navigational
purpose (e.g. Harbour) and scale of the
selected chart (see Compilation Scale in Chart
Facility).
Contours / Depths
The Contours/Depths information includes
depth and contour values for the selected chart
based on the requested values from the Chart
Depths/Heights window.
The contours of the chart will always increase to
a higher value than the minimum values set in
Chart Depths/Heights. For example, if the Deep
Contour value is increased from the default of
30 metres to a value ranging from 31 to 50
metres then the Deep Contour read-only value
will display 50.
