Hello everybody,
I got a plot like this one:
h = subplot(1,2,1);
plot(0, 0);
axis([-30 40 -20 100 ]);
grid on
Now I am getting a new array of x,y - points every second. How can I update the subplot h with these arrays? It is an n by 2 single array.
Thank you in advance!
Lucca

In your loop where you get new x,y arrays, make sure you have this line after the plot:
plot(.................
drawnow;
drawnow will force the plot to update immediately. Otherwise it probably won't get around to it until the loop is entirely finished so that all you will see is the very last set of data plotted.
