Draws labels for a particular face of a box in 3-space (for use with selected TDPACK routines).
Available in version 4.3.1 and later.
procedure tdlbla ( wks  : graphic, axis  : integer, info_label  : string, num_labels  : string, xrl_edge  : float, ybt_edge  : float, angle  : float )
A scalar integer indicating 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).info_label
A string to use as an informational label. If the string is blank (""), no informational label is written.num_labels
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.xrl_edge
A float array of 2 elements representing 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.ybt_edge
A float array of 2 elements representing 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.angle
A float scalar specifying the angle, in degrees, at which the labels are to be written. This angle is defined with reference to the current reference parallelogram.
This routine is part of the low-level TDPACK package, which is a group of Fortran and C callable routines for projecting objects from a 3-dimensional coordinate system having U, V, and W axes to a 2-dimensional projection plane having X and Y axes and/or for drawing the projections of those objects. This can be referred to somewhat loosely as "drawing objects in three dimensions".
