Chart Viewer:
DNC charts are made up of several scale ranges. The information extent of the
scale ranges varies and is determined via the penetration depth (zoom in/out).
If an object is now deleted or inserted in a scale range, this action is restricted
only to this scale range.
Previous or subsequent scale ranges are not considered in this process.
This means that deleted objects are still displayed there, new objects are
missing.
In order to avoid this missing information, the object information of the scale
ranges must be updated after deletion or addition.
After the deletion/insertion of an object, the following steps are recommended.
Select View all chart , it will display the updated object at the first navigation
purpose where this object is available centred on the chart.
The displayed dataset will be automatically be presented at the smallest scale
available.
At the same time
tree list box and the Delete Object button will be enabled.
Press on the Next button to move to next navigation purpose (e.g. harbour).
Now you can navigate through all chart scales using the Next or Prev button.
If there is no smaller scale containing the object then the Next button will be
disabled.
If you are at most detailed navigation purpose then
Prev button will be disable.
