GOGraphWidget

typedef struct _GOGraphWidget GOGraphWidget;


enum GOGraphWidgetSizeMode

typedef enum {
	GO_GRAPH_WIDGET_SIZE_MODE_FIT = 0,

} GOGraphWidgetSizeMode;


go_graph_widget_new ()

GtkWidget *         go_graph_widget_new                 (GogGraph *graph);

Creates a new GOGraphWidget with an embedded GogGraph. If graph is NULL, the graph will be auto-created, and a GogChart will be added graph.

graph :

GogGraph

Returns :

the newly created GOGraphWidget.

go_graph_widget_get_chart ()

GogChart *          go_graph_widget_get_chart           (GOGraphWidget *widget);

widget :

GOGraphWidget

Returns :

the GogChart created by go_graph_widget_new().

go_graph_widget_get_graph ()

GogGraph *          go_graph_widget_get_graph           (GOGraphWidget *widget);

widget :

GOGraphWidget

Returns :

the GogGraph embedded in the widget.

go_graph_widget_get_renderer ()

GogRenderer *       go_graph_widget_get_renderer        (GOGraphWidget *widget);

widget :

GOGraphWidget

Returns :

the GogRenderer used by the widget.

go_graph_widget_set_size_mode ()

void                go_graph_widget_set_size_mode       (GOGraphWidget *widget,
                                                         GOGraphWidgetSizeMode size_mode,
                                                         int width,
                                                         int height);

Sets the size mode of the GOGraphWidget. It is used to determine the size and position of the drawn chart. The following sizing modes are supported:

GO_GRAPH_WIDGET_SIZE_MODE_FIT, aspect ratio set. The aspect ratio is guaranteed to be maintained, i.e. the graph is never squeezed, and will always fit into the visible area.

GO_GRAPH_WIDGET_SIZE_MODE_FIT, no aspect ratio set. The aspect ratio is adapted to make the graph exactly fit into the visible area.

GO_GRAPH_WIDGET_SIZE_MODE_FIT_WIDTH, aspect ratio set. The aspect ratio is guaranteed to be maintained, i.e. the graph is never squezzed, and will always occupy the whole width of the visible area.

GO_GRAPH_WIDGET_SIZE_MODE_FIT_HEIGHT, aspect ratio set. The aspect ratio is guaranteed to be maintained, i.e. the graph is never squezzed, and will always occupy the whole height of the visible area.

GO_GRAPH_WIDGET_SIZE_MODE_FIT_FIXED_SIZE, no aspect ratio set. The graph will occupy the area specified by width/height, its aspect ratio will be determined by height/width.
