Hey there, I need to make a application in which i need to display graph for sensor reading, I am reading temerature sensor light sensor accelerator sensor. and these option is in check box, firstly when i click connect button the temperature sensor should be in graph only then when i click checkbox the line should appear in graph, when i uncheck it line should disappear, and all the line should be in single graph.

I am posting my code which is only dummy but data is live from arduino.

clear all; global a; % global p1; % global p2;

tempflag =0; global secondflag; secondflag = 0; iter =1; a = arduino('COM7', 'Uno');

% --- Executes on button press in pushbutton1. function pushbutton1_Callback(hObject, eventdata, handles) set(handles.axes1, 'Visible','on'); % %

x=0; global a; global tempflag;

while 1 % disp(tempflag);

    v=readVoltage(a,'A0');
    analog = (v/0.0048875);
    temp = -(analog * 0.48828125);
    %disp(temp);
    x = [x temp]; 
    handles.p1 = plot(handles.axes1 , x, 'color', 'blue');
    set(handles.p1, 'tag', 'p1');
     subplot(2, 2, [1 3]);
%      hold on;
%      handles.p2 = plot (handles.axes1, -x , 'color', 'red');
%      set(handles.p2, 'tag', 'p2');
    legend('Temperature','Location', 'southwest');
    xlabel('Time') % x-axis label
    ylabel('Temerature') % y-axis label
    grid;
    set(handles.edit1,'String', num2str(temp));
    pause(0.5);
end
