Editing Data Points
One may add, redefine, or remove data points directly on map. The "Objects - >
Points" menu opens a list of all data points.

A data point clicked in the list becomes red in both the basic and general view
windows. Double clicking a data point on a map selects it in the list.
The "Esc" key removes the selected data point. The "Add" button
inserts a new data point. It is not necessary to enter coordinates manually. Double
clicking on the map assigns new coordinates. New points are green and are appended to the
list. One can add data points from an appropriately formatted file.
Deleted points are marked by a cross and withdrawn from the list.
The "Change" button replaces a selected data point's values.
The "Save" button writes a data point file for subsequent use.
The edited list is employed ONLY AFTER PRESSING the "Redraw" button to update
the map. |
