function ch = plotchild(ax, dim, bfmode)
%PLOTCHILD Get plot objects in an axis
%  This function is a helper function for the plot tools and basic
%  fitting. Do not call this function directly.

%   CH = PLOTCHILD(AX) returns the list of plot object
%   children of axes AX. This function is a helper function for the
%   plot tools.
%
%   CH = PLOTCHILD(AX,DIM) for DIM=2 or 3 returns the 2D or 3D
%   children of axes AX, respectively.
%
%   CH = PLOTCHILD(AX,2,true) returns children that are compatible with
%   the basic fitting GUI.
