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.
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 :/

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])
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!
