Answer 1

I now solved it with

function z_removePlots(handles)

if (isfield(handles,'image') && isfield(handles.image,'hplot'))
    if ishandle(handles.image.hplot)
        delete(handles.image.hplot);
        delete(findall(gcf,'tag','Colorbar'));
        handles.image.hplot = 0;
        set(handles.axesImage, 'Visible', 'off');
    end
end
if (isfield(handles,'contour') && isfield(handles.contour,'hplot'))
    if ishandle(handles.contour.hplot)
        delete(handles.contour.hplot);
        handles.contour.hplot = 0;
        ClearLinesFromAxes(handles.axesContour)
        set(handles.axesContour, 'Visible', 'off');
    end
end
guidata(handles.output,handles);

with

function ClearLinesFromAxes(axisObj)
if ishandle(axisObj)
    handles2delete = get(axisObj,'Children');
    delete(handles2delete);
end
