};

struct GwyGraphLabel

struct GwyGraphLabel;

struct GwyGraphLabelClass

struct GwyGraphLabelClass {

    GtkWidgetClass parent_class;

    void (*selected)(GwyGraphLabel *label);
    
    gpointer reserved1;
    gpointer reserved2;
};

gwy_graph_label_new ()

GtkWidget*  gwy_graph_label_new             ();

creates new graph label.

Returns :

new graph label

gwy_graph_label_set_visible ()

void        gwy_graph_label_set_visible     (GwyGraphLabel *label,
                                             gboolean is_visible);

`label` :
`is_visible` :

gwy_graph_label_set_style ()

void        gwy_graph_label_set_style       (GwyGraphLabel *label,
                                             GwyGraphLabelParams style);

`label` :
`style` :

gwy_graph_label_add_curve ()

void        gwy_graph_label_add_curve       (GwyGraphLabel *label,
                                             GwyGraphAreaCurveParams *params);

Adds a curve description to label. All the information is in structure params, including line/dots sizes and text of added curve label.

`label` :	label to be changed
`params` :	curve parameters

gwy_graph_label_clear ()

void        gwy_graph_label_clear           (GwyGraphLabel *label);

Clears label - removes all the curve descriptions.

label : label to be cleared
