6.8 Moving around the chart
You can move around the chart using the pan and zoom controls.
A combination of zooming and panning is required to move around
the chart and display an area at the appropriate scale.
Note: When you pan the chart, or when you change the scale in
autorange mode; the motion mode is suspended.
Panning moves the displayed chart to a different area. When
the cursor reaches the edge of the screen, the chart pans.
When you zoom in, the chart scale changes to show a smaller
area in more detail. Conversely, if you zoom out the chart area
displayed is increased but the detail is reduced.
Note: The cartographic detail available on charts varies
according to the chart and the chart scale. Some areas provide
detail at smaller scales than others.
A feature of the chart is ‘autoscale’. If you select a chart scale that
does not have cartographic detail in some areas, the chart will use
the most detailed level available for the surrounding area and stretch
it to t the selected scale. This means that you will never have blank
or hatched areas on your screen. However there may be some
mis-alignment of objects which cross the chart boundary in this area.
