Details:

The code below should ultimately render 10 bars of random height.


 N = 10;
 xdata = 1:N;
 ydata = rand (1, N);
 h = bar (xdata (1));
 xlim ([0, 11])
 for n = 2:numel(xdata)
   set (h, "xdata", xdata(1:n), "ydata", ydata(1:n))
   drawnow ()
   pause (0.2)
 end


The fltk toolkit only renders the first bar.
