NAME¶
Labelbar_params - This document briefly describes all Labelbar internal
parameters.
DESCRIPTION¶
Labelbar has six internal parameters, each of which affects the behavior of
LBLBAR in a particular way. The current value of one of these parameters may
be retrieved by calling either LBGETI or LBGETR and the value of one of them
may be reset by calling either LBSETI or LBSETR.
Parameter descriptions, in alphabetical order, of all Labelbar internal
parameters follow. Each description begins with a line giving the parameter
name and the intrinsic FORTRAN type of the parameter.
- 'CBL' - Integer
- Color of box lines. The default value is -1.
- 'CFL' - Integer
- Color of fill lines. The default value is -1.
- 'CLB' - Integer
- Color of labels. The default value is -1.
- 'WBL' - Real
- Width of box lines. The default value is 0.
- 'WFL' - Real
- Width of fill lines. The default value is 0.
- 'WLB' - Real
- Width of label lines. The default value is 0.
Each of the "color" parameters may be given a negative value to
indicate that color is unspecified; in this case, the color of an object drawn
will be that specified by the current polyline color index (in the case of box
lines and fill lines) or the current text color index (in the case of labels).
A value which is zero or greater specifies the color index to be used.
Each of the "width" parameters may be given a value of zero or less to
indicate that line width is unspecified; in this case, the line width used to
draw an object will be that specified by the current polyline width scale
factor. Note that setting polyline width before drawing the labels does affect
their appearance; this is because labels are drawn by calls to the routine
PLCHHQ, which strokes out characters using lines.
