You say "I want the text in the text bar to show in the axes when the button is pushed."

I don't know what a text bar is, but I assume you mean your edit text field/box. I also will assume you have an axes called axes1 that has a range of 0-10 in the x direction and 0-10 in the y direction. So, just make your pushbutton4 callback look like this.

function pushbutton4_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton4 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% Get the text in the edit box:
editText = get(handles.edit1,'String')
% Make it show up in the axes at location 2,4:
text(2, 4, editText);

MATLAB: GUI

The GUIs built by GUIDE use the handles structure to share the handles for all the GUI objects, for example:

handles.edit1 %this is the handle for one edit box, edit1 is the box name
get(handles.edit1,'String') %gives you what's inside the edit box 1
%This will put your message on one text box
set(handles.text1,'String','Please enter a positive number.')

For your example you can edit the edit box callback and add a detection, for example:

if str2double(get(handles.edit1,'String'))<0
%Warn the user about the negative input
set(handles.edit1,'String','0') %put zero (default value) on the edit box 
end
