[Matlab GUI] Build simple Data Processing tool - 5/5

5. Clear the axes, and Move the figure to new figure (Undock)

After drawing a plot, you can either clear the plot or undock the plot from the axes.

1) Clear
function Clear_ClickedCallback(hObject, eventdata, handles)
% hObject    handle to Clear (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
try
    cla(all,'reset'); % Clear the entire axes and remove the y-axis
catch
    cla();
end
handles.legend = [];
legend off;
set(handles.axes1,'Position',handles.inipos);

2) Undock
function Undock_ClickedCallback(hObject, eventdata, handles)
% hObject    handle to Undock (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

warning('off');

fig_children = get(gcf,'children');
fig_Axes = findall(fig_children,'Type','Axes');
fig_legend = findall(fig_children,'Tag','legend');
fig = figure;

% copy an existing post from gui to new figure window
copyobj(fig_Axes,fig);

% Delete the legends because the size is not well-suited
dleg = findall(fig,'Tag','legend'); delete(dleg);

% Clear an offset in position of an existing post so it can be centered on a new figure window 
set(gca,'ActivePositionProperty','outerposition');
set(gca,'Units','normalized');
set(gca,'OuterPosition',[0 0 1 1]);
set(gca,'position',[0.1200 0.1100 0.790 0.8150]);

% Change the default logo on the new figure appeared.
try 
    imgPath = fullfile(pwd,'itk.jpg');
    javaFrame = get(handle(gcf),'JavaFrame');
    javaFrame.setFigureIcon(javax.swing.ImageIcon(imgPath)); 
catch
    if code == 1
        warndlg('1','error');
    elseif code == 2
        warndlg('2','error')
    end
end
% Set the legend on the new figure
l = legend('show'); set(l,'Interpreter','none');
warning('on');
