SET PIE CHART ANNOTATION DISTANCES
CALL SEQUENCE
void tset_piech_annot_dist (strid, intext, d1, d2, d3)
INPUT PARAMETERS
Pint strid;
Tpie_annot_flag intext;
Pfloat d1,d2,d3;
ARGUMENTS
- strid
- Identifier of the structure of the pie chart with the following
attributes:
- intext
- Attributes for interior or exterior annotation:
- TANNOT_INTERNAL
- Interior annotation.
- TANNOT_EXTERNAL
- Exterior annotation.
- d1
- First distance defining annotation/arrow placement (inner-most point).
- d2
- Second distance defining annotation/arrow placement (middle point).
- d3
- Third distance defining annotation/arrow placement (outer-most point).
EFFECT
This function sets the attributes that control the location of annotation on a
pie chart. For a description of how these distances are applied, see the
description of the function tset_piech_annot_pos
For interior annotation, if tset_piech_annot_dist is not called or if
d1 is negative or zero, the annotation is drawn inside the slices at
2/3 the radius of the pie chart. For exterior annotation, if
tset_piech_annot_dist is not called or if the specified distances are
negative or zero, d1 = radius*21/20, d2 = radius/10 and
d3 = radius/5.
