Answer 1

Try this:

%=====================================================================
% Erases all lines from the image axes, h.  h can be the current axes, gca.
function ClearLinesFromAxes(h)  
        %fprintf('ClearLinesFromAxes.1\n');
  axesHandlesToChildObjects = findobj(h, 'Type', 'line');
        %fprintf('ClearLinesFromAxes.2\n');
  if ~isempty(axesHandlesToChildObjects)
    delete(axesHandlesToChildObjects);
  end
  return; % from ClearLinesFromAxes

For example, to call

ClearLinesFromAxes(gca);
