INQUIRE PIE CHART ANNOTATION ARROW
CALL SEQUENCE
void tinq_piech_annot_arrow (strid, flgarr, width, height)
INPUT PARAMETERS
Pint strid;
OUTPUT PARAMETERS
Tvisibility_flag *flgarr;
Pfloat *width ;
Pfloat *height;
ARGUMENTS
- strid
- Identifier of the structure of the pie chart with the following
attributes:
- flgarr
- Visibility status of arrows.
- TVISIBILITY_OFF
- The arrows are invisible.
- TVISIBILITY_ON
- The arrows are visible.
- width
Width of the arrow pattern. This value is given in units of normalized
space, [0-1] × [0-1] (× [0-1]), defined by the function tdomain or
tdomain3.
- height
Height of the arrow pattern. This value is given in units of
normalized space, [0-1] × [0-1] (× [0-1]), defined by the function
tdomain or tdomain3.
EFFECT
This function retrieves the attributes that control the display of arrows
between slices and external annotation on a pie chart. Each arrow is composed
of two branches whose lengths are defined by the function
tset_piech_annot_dist. Each arrow is constructed based on the
positioning attributes defined by tset_piech_annot_pos
