matlab的gui图像处理操作界面，实现坐标轴重置界面

标签：Ni set string text gui 操作界面 handles matlab Ns

1.首先建立gui界面，具体过程在这里不做赘述。

 

 

 

2.然后将坐标轴所要显示的曲线放到对应的位置。

按下开始按键，即可在相应位置显示曲线

 

 

 

function push_begin_button_Callback(hObject, eventdata, handles)%开始按键的回调函数
% hObject handle to push_begin_button (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)

........（中间省略一些数据传递）

Ni_h = animatedline(handles.axes_Ni);
Ns_h = animatedline(handles.axes_Ns);

......

for k = 1:length(day)
addpoints(Ni_h,day(k),I_2(k));
str_R = sprintf('退出人数R： %d',R(k));
set(handles.text_R,'String',str_R);
drawnow
str_S2 = sprintf('健康者人数Ns： %d',S_2(k));
set(handles.text_Ns,'String',str_S2);

str_I2 = sprintf('病人人数Ni： %d',I_2(k));
set(handles.text_Ni,'String',str_I2);
addpoints(Ns_h,day(k),S_2(k));
drawnow

end

.......

 

 

3.按下清空界面，即可清楚全部数据，包括坐标轴曲线

function pushbutton_clear_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton_clear (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
axes(handles.axes_Ni); %指定需要清空的坐标轴
cla reset;
axes(handles.axes_Ns);
cla reset;

set(handles.edit_N,'string','');
set(handles.edit_S0,'string','');
set(handles.edit_I0,'string','');
set(handles.edit_lambda,'string','');
set(handles.edit_MIU,'string','');
set(handles.text_R,'string','退出人数R：               ');
set(handles.text_Ns,'string','健康者人数Ns：               ');
set(handles.text_Ni,'string','病人人数Ni：               ');

 

 完成。
