Real-Time Auto-Scrolling Graph from Serial Port
This script takes input from the Serial port 'COM4' with the baud rate of 19200 and plots a running graph with the X-axis range of 200.
I used it for my IMU sensor so the input is in the form of strings '<accX accY accZ>' (eg:- '381 328 420'), you can also add the gyro readings to it. I run the loop to 1000 iterations you can modify to suit your purpose. A better solution i will try later is to take the time inputs from your device(i used Arduino so i will possibly use micros()) to get exact time related outputs.
It is a bit slow due to the usage of 'drawnow' but i'll try it with other methods and post a better version soon.
I haven't commented it nicely cause i think the code is fairly self-explanatory.
