Reading of Slider into text box GUI

I'm displayin a signal

i have two push buttons next and back

i'm diving the signal into 3 blocks on x-axis

from 0 to 4 and from 4 to and from 8 to 12

i want to print 1 in a textbox when x-axis is from 0 to and 2 when it's 4 to 8

This code doesn't show any thing in the textbox

function Btn_Next_Callback(hObject, eventdata, handles)
% hObject    handle to Btn_Next (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
%handles.counter=handles.counter+4;
 %set(handles.axes1,'XLim',[handles.counter handles.counter+4]);
 % save the updated handles structure
 %guidata(hObject, handles);

ax = axis;
x1 = ax(1)+ 4;
x2 = ax(2) + 4;
axis ([x1 x2 ax(3) ax(4)]);

if (x1==0) && (x2==4)
 set(handles.edit5,'String' ,'1' );
end

It would only set something in the text box if your x axis minimum is -4.

Something like this would do the job, assuming you on;y want to set the text box value when the axes limits are exactly what you state.

block = [];
if ax(2) - ax(1) = 4
    if ax(1) = 0
        block = 1;
    elseif ax(1) = 4
        block = 2;
    elseif ax(1) = 8
        block = 3;
    end
    set( handles.edit5,'String' , num2str( block ) );
end
