Problem with animated line and GUI

Hello guys, im working with a guide for make 2 graphics in real time with information from bluetooth: - First for orientation information (handles.axes1) - Second for proximity information (handles.axes2)

if true
  function pb_start_Callback(hObject, eventdata, handles)
% hObject    handle to pb_start (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
global s
  line = animatedline;
  muestra=1;
  while true
      vector_datos=fscanf(s);
      datos=strsplit(vec_datos,'/');
      orientacion_str=datos{1};
      orientacion = str2double(orientacion_str);
      distancia=datos{2};
      distancia = str2double(distancia);
      axis([muestra-10,muestra,0,360])
      addpoints(line,muestra,orientacion);
      drawnow
      muestra=muestra+1;
  end
end
end

With my code i can graphic well the orientation in default (handles.axes2) axes, but i write axes(handles.axes1) and it doesnt work. I have tried already the option of animatedline('Parent', handles.axes1) and it doesnt work. My problem is that i need to get the orientation animatedline in axes1 and proximity in axes2, but i dont know where i should write axes(handles.axes1) or axes(handles.axes2).

Do you update your handle in the main figure script?

guidata(figure,handles);

As what i know, by default, handle does not pass to your callback.

i think i dont update my handle... this is my whole program:

if true

    function varargout = transmision_en_vivo(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @transmision_en_vivo_OpeningFcn, ...
                   'gui_OutputFcn',  @transmision_en_vivo_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if true
if nargout
  [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
  gui_mainfcn(gui_State, varargin{:});
end

if true
  function transmision_en_vivo_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
function varargout = transmision_en_vivo_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;
function pb_bt_Callback(hObject, eventdata, handles)
s =Bluetooth('HC-06',1);
fopen(s);
function transmision_en_vivo_OpeningFcn(hObject, eventdata, handles, varargin)
handles.output = hObject;
guidata(hObject, handles);
function varargout = transmision_en_vivo_OutputFcn(hObject, eventdata, handles) 
varargout{1} = handles.output;
end

if true
function pb_bt_Callback(hObject, eventdata, handles)
s = Bluetooth('HC-06',1);
fopen(s);
end

 if true
    function pb_start_Callback(hObject, eventdata, handles)
% hObject    handle to pb_start (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
global s
    line = animatedline;
    muestra=1;
    while true
        vector_datos=fscanf(s);
        datos=strsplit(vec_datos,'/');
        orientacion_str=datos{1};
        orientacion = str2double(orientacion_str);
        distancia=datos{2};
        distancia = str2double(distancia);
        axis([muestra-10,muestra,0,360])
        addpoints(line,muestra,orientacion);
        drawnow
        muestra=muestra+1;
    end
  end
end

if you can help me for update my handle, and choose a figure 1 for 1st animated line, and figure2 for second animatedline. Thank yoou very much!!

Hi, do you mind to re-arrange your code? It is very difficult for me to know which line is command and which line is not command.

[Rubén Maestro Huesa]

do u think the way to graphic 2 animatedlines in 2 different figures is updating handles? i can search information about it. Im new with guides and its a bit difficut for me :/

[Kevin Chng]

No problem. refer to my code, how to specify the axes for plot the animated line.

In your code, there is 'gui_OpeningFcn', @transmision_en_vivo_OpeningFcn, it has updated guidata(hObject, handles).

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)
h = animatedline(handles.axes1);
axis([0 4*pi -1 1])

for x = linspace(0,4*pi,10000)
    y = sin(x);
    addpoints(h,x,y)
    drawnow limitrate
end

To run 2 animatedlines in 2 different axes or 2 different figure?

In your code, you just need to specify the axes in line=animatedline(handles.axes1).

forgot to mention that, it is better to specify the axes for axis([muestra-10,muestra,0,360])

axis(handles.axes1,[muestra-10,muestra,0,360])

[Rubén Maestro Huesa]

i discovered today another way to work, but i think its really the same:

if true
  hAnimatedLine(1) = animatedline('Parent',handles.axes6);
  hAnimatedLine(2) = animatedline('Parent',handles.axes7);
  muestra=1;
  while true
      vector_datos=fscanf(s);
      datos=strsplit(vector_datos,'/');
      orientacion_str=datos{1};
      orientacion = str2double(orientacion_str);
      distancia=datos{2};
      distancia = str2double(distancia);
      handles.axes6.XLim = [muestra-10 muestra]
      handles.axes6.YLim = [0 380]
      handles.axes7.XLim = [muestra-10 muestra]
      handles.axes7.YLim = [0 350]
      addpoints(hAnimatedLine(1),muestra,orientacion);
      addpoints(hAnimatedLine(2),muestra,distancia);
      drawnow
      muestra=muestra+1;
  end
end

My project is working now!!! Thank you vey much for ur help!

Do you mind accept my answer if it is working for you?
