gint gtk_databox_graph_calculate_extrema	(	GtkDataboxGraph *	graph,
		gfloat *	min_x,
		gfloat *	max_x,
		gfloat *	min_y,
		gfloat *	max_y
	)

gtk_databox_graph_calculate_extrema: : A GtkDataboxGraph object : Will be filled with the lowest x value of the dataset : Will be filled with the highest x value of the dataset : Will be filled with the lowest y value of the dataset : Will be filled with the highest y value of the dataset

Virtual function which determines the minimum and maximum x and y values of the values of this GtkDataboxGraph object if applicable (there are graphs which do not contain data).

Return value: 0 on success, -1 if no data is available,

Here is the caller graph for this function:

GdkGC* gtk_databox_graph_create_gc	(	GtkDataboxGraph *	graph,
		GtkDatabox *	box
	)

gtk_databox_graph_create_gc: : A GtkDataboxGraph object : A GtkDatabox object

Virtual function which creates a graphics context for the .

Typically called by derived graph objects when the graphics context is needed for the first time.

Return value: The new graphics context.

void gtk_databox_graph_draw	(	GtkDataboxGraph *	graph,
		GtkDatabox *	box
	)

gtk_databox_graph_draw: : A GtkDataboxGraph object : A GtkDatabox object

Virtual function which draws the GtkDataboxGraph on the drawing area of the GtkDatabox object.

Typically this function is called by GtkDatabox objects.

GdkColor* gtk_databox_graph_get_color

(

GtkDataboxGraph *

graph

)

gtk_databox_graph_get_color: : A GtkDataboxGraph object

Gets the current color of the graph elements (e.g. points).

Return value: The color of the graph.

GdkGC* gtk_databox_graph_get_gc

(

GtkDataboxGraph *

graph

)

gtk_databox_graph_get_gc: : A GtkDataboxGraph object

Gets the current graphics context of the graph.

Return value: The current graphics context of the graph.

gboolean gtk_databox_graph_get_hide

(

GtkDataboxGraph *

graph

)

gtk_databox_graph_get_hide: : A GtkDataboxGraph object

Gets the current "hide" status.

Return value: Whether the graph is hidden (true) or not (false).

gint gtk_databox_graph_get_size

(

GtkDataboxGraph *

graph

)

gtk_databox_graph_get_size: : A GtkDataboxGraph object

Gets the size of the graph elements (e.g. the line width).

Return value: size of the graph elements

GType gtk_databox_graph_get_type

(

void

)

void gtk_databox_graph_set_color	(	GtkDataboxGraph *	graph,
		GdkColor *	color
	)

gtk_databox_graph_set_color: : A GtkDataboxGraph object : Color which is to be used by the graph object

Sets the color which the GtkDataboxGraph object is supposed to be using when drawing itself.

void gtk_databox_graph_set_gc	(	GtkDataboxGraph *	graph,
		GdkGC *	gc
	)

gtk_databox_graph_set_gc: : A GtkDataboxGraph object : Graphics contex for the graph object

Sets the graphics context which the GtkDataboxGraph object is supposed to be using when drawing itself.

void gtk_databox_graph_set_hide	(	GtkDataboxGraph *	graph,
		gboolean	hide
	)

gtk_databox_graph_set_hide: : A GtkDataboxGraph object : Declares whether should be hidden (true) or not (false).

Hidden graphs are not shown, when the GtkDatabox containing them is redrawn.

void gtk_databox_graph_set_size	(	GtkDataboxGraph *	graph,
		gint	size
	)

gtk_databox_graph_set_size: : A GtkDataboxGraph object : Size of graph elements for the graph object

Sets the size (e.g. line width) which the GtkDataboxGraph object is supposed to be using when drawing itself.
