tdlbla(3NCARG)


NAME

   TDLBLA - This routine is called to put labels on a particular edge of a
   box.

SYNOPSIS

   CALL TDLBLA (IAXS, ILBL, NLBL, XAT0, XAT1, YAT0, YAT1, ANGD)

C-BINDING SYNOPSIS

   #include <ncarg/ncargC.h>

   void c_tdlbla(int iaxs, char* ilbl, char* nlbl, float xat0, float xat1,
   float yat0, float yat1, float angd)

DESCRIPTION

   It is assumed that TDPARA has been called to define the reference
   parallelogram to be a rectangle in 3-space lying in one corner of one
   face of the box being labelled. The sides of this rectangle are assumed
   to be vectors of length 1 (that is to say, the rectangle defines a unit
   square within that face of the box). It is also assumed that the value
   of the internal parameter 'CS2' has been set in the same way that
   TDLBLS would reset it, using a code sequence like

     CALL TDGETR ('CS1',CSM1)
     CSM2=CSM1*MIN(UMAX-UMIN,VMAX-VMIN,WMAX-WMIN)
     CALL TDSETR ('CS2',CSM2)

   (where UMIN, UMAX, VMIN, VMAX, WMIN, and WMAX are as defined for a call
   to TDLBLS).

   The arguments of TDLBLA are as follows:

   IAXS    (an input expression of type INTEGER) - says which edge of the
           face is being labelled (1 => left, 2 => right, 3 => bottom, and
           4 => top, where the meanings of "left", "right", "bottom", and
           "top" are defined by the orientation of the reference
           parallelogram).

   ILBL    (input, of type CHARACTER) - a string to be used as an
           informational label.  If the string is blank, no informational
           label is written.

   NLBL    (input, of type CHARACTER) - a string containing numeric
           labels. The labels need not be in any particular order, but
           they have to be separated by blanks and each has to be readable
           using a FORTRAN format of the form "En.0", where "n" is the
           length of the label. If the string is blank, no informational
           label is written.

   XAT0 and XAT1
           (input expressions of type REAL) - the values of "X" associated
           with the left and right edges of the face being labelled, where
           "left" and "right" are defined in terms of the current
           reference parallelogram.

   YAT0 and YAT1
           (input expressions of type REAL) - the values of "Y" associated
           with the bottom and top edges of the face being labelled, where
           "bottom" and "top" are defined in terms of the current
           reference parallelogram.

   ANGD    (an input expression of type REAL) - specifies the angle, in
           degrees, at which the labels are to be written. This angle is
           defined with reference to the current reference parallelogram.

C-BINDING DESCRIPTION

   The C-binding argument descriptions are the same as the FORTRAN
   argument descriptions.

ACCESS

   To use TDLBLA or c_tdlbla, load the NCAR Graphics libraries ncarg,
   ncarg_gks, and ncarg_c, preferably in that order.
