Answer 1

Another approach:

y1 = rand(1, 100);
y2 = rand(1, 200) * 2;
AxesH = axes('NextPlot', 'add');
Plot1H = plot(y1);
pause(2.0);
set(AxesH, 'XLimMode', 'manual', 'YLimMode', 'manual');
Plot2H = plot(y2, 'r');

Or you can replace the XData and YData of the plotted line directly instead of the last line:

set(Plot1H, 'XData', 1:200, 'YData', rand(1, 200));
