Continually updating graph/ Dynamic Graph/ Live Graph

19 views (last 30 days)
I am able to continually extract a value from my Raspberry Pi (every 5 seconds) and store it into MATLAB workspace as variable A (over-writes the previous value of A every 5 seconds). Now I would like to plot a graph where A is on the y-axis and time is on the x-axis and it is continually plotting the updated value of A (every 5 seconds) until I stop the program.
Is there anyway to do this? If so, what would the code be to accompish this?

Yes, you can do that. Use linkdata, which allows automatically update graphs when variables change.

But I am looking for my x-axis (time) to go from 0 to infinity, while plotting the y-axis (value of A) every 5 seconds. Could you please give an example of similar code?

use tic toc to get the time, then update the graph with respect to A value. Please wait for experts commnets or other answer.
