NAME

6       Labelbar_params - This document briefly describes all Labelbar internal
7       parameters.
8

DESCRIPTION

10       Labelbar has six internal parameters, each of which affects the
11       behavior of LBLBAR in a particular way. The current value of one of
12       these parameters may be retrieved by calling either LBGETI or LBGETR
13       and the value of one of them may be reset by calling either LBSETI or
14       LBSETR.
15
16       Parameter descriptions, in alphabetical order, of all Labelbar internal
17       parameters follow. Each description begins with a line giving the
18       parameter name and the intrinsic FORTRAN type of the parameter.
19
20       'CBL' - Integer
21              Color of box lines. The default value is -1.
22
23       'CFL' - Integer
24              Color of fill lines. The default value is -1.
25
26       'CLB' - Integer
27              Color of labels. The default value is -1.
28
29       'WBL' - Real
30              Width of box lines. The default value is 0.
31
32       'WFL' - Real
33              Width of fill lines. The default value is 0.
34
35       'WLB' - Real
36              Width of label lines. The default value is 0.
37
38       Each of the "color" parameters may be given a negative value to
39       indicate that color is unspecified; in this case, the color of an
40       object drawn will be that specified by the current polyline color index
41       (in the case of box lines and fill lines) or the current text color
42       index (in the case of labels). A value which is zero or greater
43       specifies the color index to be used.
44
45       Each of the "width" parameters may be given a value of zero or less to
46       indicate that line width is unspecified; in this case, the line width
47       used to draw an object will be that specified by the current polyline
48       width scale factor.  Note that setting polyline width before drawing
49       the labels does affect their appearance; this is because labels are
50       drawn by calls to the routine PLCHHQ, which strokes out characters
51       using lines.
