MATLAB GUI axes(handles.axes1) does not work?

Hello;

I have this simple code that is supposed to draw the line having its slope and y intercept. But when I use axes(handles.axes1);

nothing happens. What should I do?

Can you post a self-contained example that we can run that shows what you mean, in context?

The GUI has a, b, c as edit text. When Solve push button is pressed, it should draw ax+by=c line on axes1.

function solve_Callback(hObject, eventdata, handles)
% hObject    handle to solve (see GCBO)
% eventdata  reserved - to be defined in atext future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

a=str2num(get(handles.a,'String'));
b=str2num(get(handles.b,'String'));
c=str2num(get(handles.c,'String'));
int=num2str(c/b);
slope=num2str(-a/b);

set(handles.y,'String',int)
set(handles.slope,'String',slope)

x=0:10;
y=c/b-a/b*x;
axes(handles.axes1);

xlabel('x');
ylabel('y');

guidata(hObject,handles);

axes() just switches focus to that particular axes control. It does not actually do any plotting at all. For that you'll need to use the plot() function

plot(x, y, 'bo-', 'LineWidth', 2, 'MarkerSize', 10);
grid on;
axis on;
ylabel('Y', 'FontSize', 30);
xlabel('X', 'FontSize', 30);

I did this, but again it shows nothing on my axis1

I do it all the time, so there's something you're not telling me - some code you're not sharing. You need to examine what the values of x and y are. Please learn how to use the debugger so you can quickly solve these yourself rather than the slow and tedious method of "debugging via the Answers forum": http://blogs.mathworks.com/videos/category/gui-or-guide/

Dear, I have used the same code and I draw the line but I need two line of the same graph. Do anyone help me how I update this code to two line. TIA

hold on
plot(x2, y2);
