     RMvertex2D (*appgridfunc)(int i) - a handle to a caller-supplied
        function that returns an RMvertex2D (x, y) corresponding to the
        grid point (i) (input).

     float (*appu1func)(int i) - a handle to caller-supplied function that
        returns a lower bound float for the upper pair at the grid point
        (i) (input).

     float (*appu2func)(int i) - a handle to caller-supplied function that
        returns a upper bound float for the upper pair at the grid point
        (i) (input).

     float (*appl1func)(int i) - a handle to caller-supplied function that
        returns a lower bound float for the lower pair at the grid point
        (i) (input).

     float (*appl2func)(int i) - a handle to caller-supplied function that
        returns a upper bound float for the lower pair at the grid point
        (i) (input).

     float (*appdata2func)(int i) - a handle to a caller-supplied function
        that returns a scalar value for the grid point (i).  This value is
        used in conjunction with the RMvismap to compute vertex color.

     RMvisMap *vmap - a handle to an RMvisMap object (input).

     int axis_offset_flag - an RMenum specifying in which axis to
        offset the glyph.  Must be one of RMV_XAXIS_OFFSET,
        RMV_YAXIS_OFFSET (input).

     int npts - int specifying number of grid data points (input).

     RMenum linewidth_enum - an RMenum specifying the line width.  Must be
        one of RM_LINEWIDTH_NARROW, RM_LINEWIDTH_MEDIUM,
        RM_LINEWIDTH_HEAVY, or RM_LINEWIDTH_[1..8] (input).

     RMenum linestyle_enum - an RMenum specifying the lline style.  Must
        be one of RM_LINES_SOLID, RM_LINES_DASHED, RM_LINES_DOTTED,
        RM_LINES_DOT_DASH, or RM_LINES_DASH_DASH_DOT (input).

     RMnode *n - a handle to an RMnode (modified).

Creates an "error bar" plot for indicating data ranges. Pairs of error bars are plotted from the four caller-supplied functions, {u1, u2, l1, l2}. These functions return a data value for a given grid point and indicate a pair of data ranges {[l1..l2], [u1..u2]}. The secondary data function can be used with the RMvisMap to color the error bars.

Upon success, RM_CHILL is returned to the caller and the error plot geometry has been added to the RMnode. Otherwise, RM_WHACKED is returned.
