## Description

GwySelectionGraphLine is used to represent signle coodinate (`x` or `y` ) graph selections. Selection data consists of signle coordinates.

If you obtain the selection from a graph widget it has the "orientation" property set for information. The orientation should be kept intact in this case as changing it is not meaningful. The graph keeps two distinct horizontal and vertical selection objects.
