a contour map is created from only one selected series. To select
the series you want to contour, Double-click the name of series in
the POINTS tree item on the Map Menu on the left to select this series.

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.
You can also 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Deleted points are marked by a cross and withdrawn from the list.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 the edited data point file for
