SET PIE CHART ANNOTATION ARROW
CALL SEQUENCE
void tset_piech_annot_arrow (strid, flgarr, width, height)
INPUT PARAMETERS
Pint strid;
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 sets the attributes that control the display of arrows between
slices and external annotation on a pie chart. If
tset_piech_annot_arrow is not called, the arrows are visible
(flgarr=TVISIBILITY_ON) and the arrow pattern has a width of
0.015 and a height of 0.015. 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 .
