GOLineDashSequence

typedef struct {
	double		 offset;
	unsigned int	 n_dash;
	double		*dash;
} GOLineDashSequence;

double offset;

offset from start.

unsigned int n_dash;

number of values in dash fields

double *dash;

lengths of the dashes segments. See cairo_set_dash() for details.

GO_ARROW_TYPE

#define GO_ARROW_TYPE (go_arrow_get_type())


go_line_dash_as_label ()

char const 		*      go_line_dash_as_label               (GOLineDashType type);

type :

a GOLineDashType

Returns :

a pointer to the user readable name of the dash type, or the name of GO_LINE_NONE if type is invalid. The returned string should not be freed.

go_line_dash_as_str ()

char const 		*      go_line_dash_as_str                 (GOLineDashType type);

type :

a GOLineDashType

Returns :

a pointer to the nickname of the dash type, or "none" if type is invalid. The returning string should not be freed.

go_line_dash_from_str ()

GOLineDashType      go_line_dash_from_str               (char const *name);

name :

Name of the dash type

Returns :

a GOLineDashType corresponding to name, or GO_LINE_NONE if not found.

go_line_dash_get_length ()

double              go_line_dash_get_length             (GOLineDashType type);

type :

GOLineDashType

Returns :

the unscaled length of the dash sequence.

go_line_dash_get_sequence ()

GOLineDashSequence * go_line_dash_get_sequence          (GOLineDashType type,
                                                         double scale);

type :

a GOLineDashType

scale :

dash scale

Returns :

a struct containing the dash sequence corresponding to type, or NULL if type is invalid or equal to GO_LINE_NONE. The lengths are scaled according to scale.

go_line_dash_sequence_free ()

void                go_line_dash_sequence_free          (GOLineDashSequence *sequence);

Frees the dash sequence struct.

sequence :

a GOLineDashSequence

go_line_interpolation_as_label ()

char const 		*      go_line_interpolation_as_label      (GOLineInterpolation type);

type :

an interpolation type

Returns :

a pointer to the label of type, or the name of GO_LINE_INTERPOLATION_LINEAR if type is invalid. The returned string should not be freed.

go_line_interpolation_as_str ()

char const 		*      go_line_interpolation_as_str        (GOLineInterpolation type);

type :

an interpolation type

Returns :

a pointer to the nickname of type, or "linear" if type is invalid. The returned string should not be freed.

go_line_interpolation_auto_skip ()

gboolean            go_line_interpolation_auto_skip     (GOLineInterpolation type);

type :

an interpolation type

Returns :

TRUE if the line interpolation type forces skipping invalid data, FALSE if it is only optional.

go_line_interpolation_from_str ()

GOLineInterpolation go_line_interpolation_from_str      (char const *name);

name :

an interpolation type nickname

Returns :

a GOLineInterpolation corresponding to name, or GO_LINE_INTERPOLATION_LINEAR if not found.

go_line_interpolation_supports_radial ()

gboolean            go_line_interpolation_supports_radial
                                                        (GOLineInterpolation type);

type :

an interpolation type

Returns :

TRUE if the line interpolation type can be used with radial axes set, FALSE it it can't.
