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.
