captions — draw graph captions
hl=captions(h, strings [,location])
vector of handles on polyline entities.
n vector of strings, strings(i) is the caption of the ith polyline
a handle of type "Legend", points to the
structure containing all the captions information (see legend_properties.
a character string with possible values:
"in_upper_right" : captions are drawn
in the upper right corner of the axes box.
"in_upper_left": captions are drawn in
the upper left corner of the axes box.
"in_lower_right": captions are drawn in
the lower right corner of the axes box.
"in_lower_left": captions are drawn in
the lower left corner of the axes box.
"out_upper_right": captions are drawn
at the right of the upper right corner of the axes box.
"out_upper_left": captions are drawn at
the left of the upper left corner of the axes box.
"out_lower_right": captions are drawn
at the right of the lower right corner of the axes box.
"out_lower_left": captions are drawn at
the left of the lower left corner of the axes box.
"upper_caption": captions are drawn
above the upper left corner of the axes box.
"lower_caption": captions are drawn
below the lower left corner of the axes box. This option
correspond to the leg argument of plot2d
"by_coordinates": the upper left corner
of the captions box is given by the "position" field of the
associated data structure. The x and
y positions are given as fractions of the
axes_bounds sizes.
Puts captions on the current plot at the in the bottom left corner
of the graphic window using the specified strings as labels.
captions prepends labels by a recall of the
corresponding polylines. The type and properties are recovered from the
given handles:
The captions function creates a Legend data structure.
There is at most one Legend associated with each
axes. If the caption function is recalled while a
Legend still exist the old one is replaced.
