The output of four sensors has been acquired using arduino and I need to make a real time plot for it in MATLAB.I have attached the images for your reference.The first image is output of 4 sensors that is acquired in arduino When I made a MATLAB coding for it only the first plot appeared and the other three sensor data was not plotted.So I made a small change by adding some variables in between,I have attached an image for it and this is the second image.While I was doing in this way, only the first two sensor data was acquired.Kindly suggest me with the changes to be made and will I lose any data if I am plotting by this code or should I use multithreading concept.

Hi I've attached code that I have used in the past to graph values from the Arduino, it should get you started. It should be noted that I was using this code before the Arduino support package was around so I am getting data/ connecting to Arduino in a different way so you will need to change that.
