This is an evergreen question. Please search for "sharing GUI" in this forum to find a bunch of solutions.

The object you have to share is the handle of the AXES object you want to plot in. So get the MainGUI's handle from the SubGUI, use it to obtain the handles struct by GUIDATA, and plot from the code of the SubGUI using the AXES' handle as 'Parent' property.

function MainGUI
handles.GuiH = figure('Name', 'Main', 'Tag', 'myMainGUI');
uicontrol('Style', 'PushButton', 'Position', [10, 10, 100, 25], ...
          'String', 'Start SubGUI', 'Callback', @StartSubGUI);
handles.TextH = uicontrol('Style', 'Text', 'Position', [10, 50, 100, 25]);
guidata(handles.GuiH, handles);  % Store handles struct in figure
end
function StartSubGUI(ButtonH, EventData)
handles = guidata(ButtonH);  % Obtain handles struct store in figure
handles2.SubGuiH   = figure('Name', 'SubGUI');
handles2.MainGuiH  = handles.GuiH;
handles2.MainTextH = handles.TextH;
handles2.TextH     = uicontrol('Style', 'Text', 'Position', [10, 50, 100, 25], ...
                          'Callback', @SubTextCB);
guidata(handles2.SugGuiH, handles2);
end
function SubTextH(TextH, EventData)
handles2 = guidata(TextH);
% Copy the text to the main gui:
set(handels2.MainTextH, 'String', get(TextH, 'String'));
% Store the string in the main gui's application data:
handles = guidata(handles2.MainGuiH);
handles.TextFromSub = get(TextH, 'String');
guidata(handles2.MainGuiH, handles);
end

Now the text typed in the sub GUI is available in the main GUI also, either in the text field or in the handles struct. Choose the solution you prefer.

Alternatively you can use the 'UserData' of the main figure, or the set/getappdata commands. The general idea remains: Provide the handle of the main GUI to the callbacks of the sub GUI.

If you have created the GUIs by GUIDE, forwarding the handles is much harder. Then you can search the handles on the fly:

function SubTextH(TextH, EventData)
MainGuiH = findobj(allchild(groot), 'flat', 'Tag', 'myMainGUI');
if isempty(MainGuiH)
  error('Main GUI is not found.');
end
handles = guidata(MainGuiH);
... same as above

% you've written 'Edit1' instead of 'handles.Edit1'

button_state = get(hObject,'Value');
if button_state == get(hObject,'Max')
set(handles.Edit1,'Visible','off')
elseif button_state == get(hObject,'Min')
set(handles.Edit1,'Visible','on')  
end
