The hardware gives data every 1/512 sec. There should be no conflict even though the Arduino101 board is not listed. However, the best way to represent points in time is by using the datetime data. and when i plot the result in realtime (as is it going through the for loop) rather than plotting y versus time, it is plotting two point (1,time) and (2,y) and draws a line in between. Ideally I would like to be able to run a matlab. com/products/interfaces/sdaq/). Is there a way to make this process. Streaming is still available as part of Chart Studio Enterprise. This tutorial will give you a basic idea about how to plot real time graph using MATLAB. Learn more about excel, real time data MATLAB. I am trying to display the data real time.
