如何用matlab中gui画图

我想设计一个GUI，点击按钮后就能画出相应的图像来，但是我不知道怎么给按钮添加这些功能。

function pushbutton1_Callback(hObject, eventdata, handles)% hObject handle to pushbutton1 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA)
% --- If Enable == 'on', executes on mouse press in 5 pixel border.% --- Otherwise, executes on mouse press in 5 pixel border or over pushbutton1.function pushbutton1_ButtonDownFcn(hObject, eventdata, handles)
x=0:0.1:2*piy=sin(x)plot(x,y)

% hObject handle to pushbutton1 (see GCBO)% eventdata reserved - to be defined in a future version of MATLAB% handles structure with handles and user data (see GUIDATA)
callback到底怎么写啊？它的格式是什么样的？和普通的语句有什么大的差别吗？
我该如何实现这个
请高手为我解答，谢谢了！

Answer 1

把画图命令放到回调函数下 也就是callback里面

Answer 2

Action,Event或别的什么东东，对button添加事件

追问

那么callback是干什么用的？还有请问event，action怎么用啊？
