In the Add Marker dialog options for the maker can be configured such as; shape, image
(from a preset or loaded bitmap), size, colour, font colours, comment and coordinates. Once
configured, clicking on Ok will lay the marker on the chart.
Several markers can be created and laid onto the chart. The markers will be stored in the
Seanet Pro configuration and so closing down and re-opening Seanet Pro will result in the
markers being re-loaded as well.
The markers can be edited, cleared, saved or loaded by right-clicking on the chart and
selecting Markers from the pop-up menu.
Note
To edit or delete a marker it is necessary to right-click directly over the marker.
