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

GSList * gog_graph_get_supported_image_formats (void);
Builds a list of supported formats for image export.
| Returns : | a GSList of GOImageFormat. | 
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_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_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.
