MATLAB: How to get specific axes handle in GUI with more then one axes

axesguiMATLABmatlab gui

Say I have GUI_1 with several axes. Now I start GUI_2 changes some settings and the corresponding axes in GUI_1 should change corresponding to the changes in GUI_2. Problem is I can't get the right axes-handle to refresh the correct axes.

findobj(HandleToGUI_1, 'type', 'axes')

gives me all axes and…

findobj(HandleToGUI_1, 'type', 'axes', '-and', 'Tag', 'TagForMySpecificAxes')

doesn't work…

How can I get the handle for my specific axes?

If the figure was created by GUIDE:

handles_GUI1 = guidata(HandleToGUI_1);
handles_GUI1.TagForMySpecificAxes   % May be called specifically, perhaps 'axes_<TAG>'

You can store the wanted object manually by guidata also, when you do not use GUIDE. Using an already stored handle is faster than searching dynamically. If there is a huge number of elements in the GUI (hundreds), the delay is noticable.

MATLAB: Adding axes title using the GUI popupmenu

Sophie - if we assume that your GUI has (at least) a popup menu and an axes (and that the GUI has been created in GUIDE), then I would use the popup menu callback to update the axes title whenever the user selects a new menu item. For example,

function popupmenu1_Callback(hObject, eventdata, handles)
itemStrings = get(hObject,'String');
selectedItem = get(hObject,'Value');
title(handles.axes1,itemStrings{selectedItem});

The above assumes that your popup menu is tagged/named popupmenu1 and your axes is named axes1. Try the above and see what happens!
