Matlab only receives 1 arduino data

I want to graph some data that comes from arduino to matlab but, I only graph 1 data from the series of data that I have, why? thank you very much for reading me

<<<<<<<<<<<<<<<<<<CODE>>>>>>>>>>>>>>>>>>>>>>>>>><<

function Matlab_Arduino
close all;
clc;
y=zeros(1,1000); %Vector donde se guardaran los datos
%Inicializo el puerto serial que utilizare
delete(instrfind({'Port'},{'COM13'}));
puerto_serial=serial('COM13');
puerto_serial.BaudRate=9600;
warning('off','MATLAB:serial:fscanf:unsuccessfulRead');

%Abro el puerto serial
fopen(puerto_serial);




figure('Name','Serial communication: Matlab + Arduino')
title('SERIAL COMMUNICATION MATLAB+ARDUINO');
xlabel('time');
ylabel('aceleration');
grid on;
hold on;

%graph

    ylim([0 100]);
    xlim([0 100]);
    aceleracion=fscanf(puerto_serial,'%d');
    plot(aceleration,'X-r');



fclose(puerto_serial);
delete(puerto_serial);
clear all;
end

By default, fscanf() only reads until the first terminator. When data is sent from arduino serial port, it is most common to send only one data point per packet.

You will need to loop reading data and adding it to the graph. I recommend that you look at animatedline()

[Erwin Avendaño]

I guess to go through the reading data with animatedline can I not?

Use readline instead of fscanf command

[Walter Roberson]

The question involved use of serial() objects. As of R2025a pre-release, serial() objects are still supported (but are due to be removed any day now.)

serial() objects do not have a readline() method, so fscanf() or fgetl() are still the appropriate functions for serial() objects.

[Oscar]

But so far it's easier., thanks for your comment.

[Walter Roberson]

If you construct a serial() object, then readline() applied to the serial() object is simply not defined.

serial() objects are not recommended, having been functionally replaced by serialport() objects. readline() is defined for serialport() objects.
