I'm new but I have made this possible by having all the .m and . fig file in same folder.
For example I have 3 GUI named TEST, TABLE and GRAPH in the main gui test I have 2 push button named table and graph
I just write the fig name on the button callback and it works.
function table_pb_Callback(hObject, eventdata, handles)
% hObject handle to table_pb (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
TABLE
% --- Executes on button press in graph_pb.
function graph_pb_Callback(hObject, eventdata, handles)
% hObject handle to graph_pb (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
GRAPH
hope i helped.
