Description

GwySelectionGraph1DArea is used to represent horizontal or vertical graph region selections in graphs. Selection data consists of coordinate pairs (from, to).

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.

gwy_selection_graph_1darea_new (void);

Creates a new 1darea-wise graph selection.
