Hi,

I'm trying to add push buttons to my figure. The first is to clear my figure and the second is to run it again. I already git the clear button but struggeling the program the start button.

My program got a rectime of 10 sec. and is live plotting my acceleration with im getting from a sensor. Can someone help me and sorry for my english I'm a native speaker

This is my Code

if true
clear all;
close all;

samplerate = 10; %Hz samples = 100; rectime = samples/samplerate;

% Find a serial port object. obj1 = instrfind('Type', 'serial', 'Port', 'COM3', 'Tag', '');

% Create the serial port object if it does not exist % otherwise use the object that was found. if isempty(obj1) obj1 = serial('COM3'); else fclose(obj1); obj1 = obj1(1); end

% Connect to instrument object, obj1. fopen(obj1);

% Configure instrument object, obj1. set(obj1, 'BaudRate', 115200); set(obj1, 'Terminator', {'LF','LF/CR'});

% Communicating with instrument object, obj1. i=0;

data={};

 %uicontrol('Style','pushbutton','String','Start','Callback','uiresume(gcbf)');  
btn = uicontrol('Style', 'pushbutton', 'String', 'Clear',...
        'Position', [20 20 50 20],...
        'Callback', 'cla');
btn = uicontrol('Style', 'pushbutton', 'String', 'Start',...
        'Position', [20 0 50 20],...
        'Callback', '');
 subplot(1,1,1)
 title('Acc X')

while (i <7)

    fscanf(obj1,'%c');
    i = i+1;
end

x_co = 1; t = x_co-1;

while (i < 108)

    gyr_box = fscanf(obj1,'%c');
    gyr_box_array = strsplit(gyr_box,',');
    acc_box = fscanf(obj1,'%c');
    acc_box_array = strsplit(acc_box,',');
