Chart Filtering Options
The chart Index table includes the following filter options: Usage Level and
Database .
All charts are defined with a usage level (e.g.
Harbour or Coastal) with each usage level
displayed in a particular colour. All the usage
types are listed in a
Usage Level drop down
list, which defaults to displaying all. To display
only the charts with a specific type of usage
level select the level from the drop down list, the
table is re-drawn showing only those charts that conform to that usage
level.
To display only the charts from a specific database click on the
Database
drop down arrow and select from the list. The table is re-drawn showing
only those charts assigned to that database.
Chart Outlines
To display chart outlines, tick the Draw Chart
Outlines check box. The display will show the
coverage of the charts within the current display
area as a series of coloured chart boundary
rectangles, the colour of the chart boundary is
dependent on the chart usage level.
Chart Selection
Individual charts may be located and identified on
the video circle. To select a chart tick the
Chart Selection Cursor check
box and move the cursor to the video circle, the letters SEL are added to
the cursor. Note that the chart selection cursor is temporary, after a period
of 10 to 15 seconds the cursor reverts to normal and the check box goes
back to unticked.
Click in an area of the video circle. The outline of
the chart is drawn and its area displayed in
colour (the colour of the outline and area is
dependent on the chart's usage level). The chart
is also highlighted in the Index list.
