A graph (in the abstract sense) in GOffice is an hierarical object model, with a GogGraph object as the top-level object. Objects that can be part of a graph is a subclass of GogObject. Those, and related objects have the prefix "Gog" in the class name. See GogObject for how to manipulate the object model, and the individual classes for specifics.
A GogGraph can have 1 or more children in the roles "Chart" and "Title".
gboolean gog_graph_export_image (GogGraph *graph
,GOImageFormat format
,GsfOutput *output
,double x_dpi
,double y_dpi
);
Exports an image of graph
in given format
, writing results in a GsfOutput stream.
If export format type is a bitmap one, it computes image size with x_dpi, y_dpi and
graph
size (see
).gog_graph_get_size()

void
gog_graph_force_update (GogGraph *graph
);
Do an update now if one has been queued.
GODoc *
gog_graph_get_document (GogGraph *graph
);
Retrieves the GODoc for graph
.
void gog_graph_get_size (GogGraph *graph
,double *width
,double *height
);
FIXME Returns the logical size of graph, in points.
GSList *
gog_graph_get_supported_image_formats (void
);
Builds a list of supported formats for image export.
gboolean
gog_graph_request_update (GogGraph *graph
);
queue an update if one had not already be queued.
GOData * gog_graph_ref_data (GogGraph *graph
,GOData *dat
);
dat
or something equivalent to it that already exists in the graph.
Otherwise use dat
. Adds a gobject ref to the target and increments a
count of the number of refs made from this GogGraph.
[transfer full]
void gog_graph_render_to_cairo (GogGraph *graph
,cairo_t *cairo
,double w
,double h
);
Renders a graph using cairo
. w
and h
are the requested width an height of the rendered graph, in the current cairo
coordinate space. This function is not suited for multiple rendering of the same graph. gog_renderer_render_to cairo or gog_renderer_update/gog_renderer_get_cairo_surface should be used instead.
void gog_graph_set_size (GogGraph *graph
,double width
,double height
);
Sets the logical size of graph, given in points.
gboolean
gog_graph_validate_chart_layout (GogGraph *graph
);
Check the layout of the chart grid and ensure that there are no empty cols or rows, and resize as necessary
void gog_graph_view_handle_event (GogGraphView *gview
,GdkEvent *event
,double x_offset
,double y_offset
);
Handle events.
void gog_graph_view_set_selection (GogGraphView *gview
,GogObject *gobj
);
Sets gobj
as current selection. If gobj
is different from previously
selected object, a selection-changed signal is emitted.
