Hi. I am trying to plot sensor data in realtime using the animated line function. I want to plot the timestamp when the data is updated against each sensor value on the x axis. I have tried the code below for the x axis:
g=datetime("now");
b=datenum(g);
addpoints(app.h,b,app.count);
drawnow;
The problem is the x axis labels are displaying as number 7.388....×10^5. Please assist

It's because you're turned your datetime type variable into a datenum and plotted that. Datenums are the number of days since January 0, 0000. animatedline is not datetime aware insofar as I'm aware. You're probably going to have to format your own XLabels to use date strings for find a helper function to do the relabeling for you.
Or, use a standard plot instead of animatedline since plot is datetime aware.
