How to plot a graph with x and y axis input live from two hardware (arduino and laser gauge- UART)

Hi,

I'm a newbie to matlab. I'm trying to plot a graph where realtime data is received from a laser gauge using serial input (FT232), and pressure reading from a sensor using arduino. I tried to interface both the hardware to arduino but it wasn't an option recommended by the tech for the laser gauge and wasn't working.Serial signal was verified to work with tera term. Now I built up a code to receive that in matlab. I would like some help on how to now integrate that code to plot where the x axis is the source from arduino.

%
close all; 
%serial object
s = serialport('COM4','BaudRate',9600);
% open serial port
fopen(s);
%plotting data
i=1;
while (1)
    data (i) = str2double(fscanf(s));
    if i <= 150
        plot(data);
    else
        plot(data(end-150:end));
        ylim([0 5]);
        pause(0.01);
        i=i+1;
    end

I suggets you use animatedLine() and addpoints() . Your current code will take increasing long to add new data points.

Is it possible to get the data for the x and y axis from the hardware to plot the graph for 7 seconds and then stay idle?

record the start time. Loop as long as etime() is less than 7 seconds.
