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.

                                                         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.

The "aspect-ratio" property

  "aspect-ratio"             gdouble               : Read / Write / Construct

Aspect ratio for rendering the graph, used only if greater than 0.

Default value: -1

The "graph" property

  "graph"                    GogGraph*             : Read / Write / Construct Only

The graph to render.

The "hres" property

  "hres"                     gdouble               : Read / Write / Construct Only

Assumed horizontal screen resolution in pixels per inch.

Allowed values: >= 1

Default value: 96

The "vres" property

  "vres"                     gdouble               : Read / Write / Construct Only

Assumed vertical screen resolution in pixels per inch.

Allowed values: >= 1

Default value: 96
