Suptitle of an updating plot

Hi to all,

I have a figure in which I have 2 plots (subplot 211 and subplot 212).

I need to impose a suptitle on the plot and the problem is that I update at every cycle the axes and for this reason the suptitle is blinking because, I think, written on the figure on every iteration.

Is there a way to impose it once for all?

Thanks, Fab.

could you paste the code you are using, please? It would be easier to give you advise if we know what you are doing.
