xlist = [];
ylist = [];
myline = line('LineStyle', '-', 'Marker', '*', 'Color', 'b'); %use appropriate properties
set(gca, 'xlim', [0 1000], 'YLim', [-10 35]);
for K = 1 : 1000
newx = K + randn();
newy = sqrt(newx) + sin(newx);
xlist = [xlist, newx];
ylist = [ylist, newy];
if length(xlist) > 20
xlist = xlist(end-19:end);
ylist = ylist(end-19:end);
set(myline, 'XData', xlist, 'YData', ylist);
Note: although it is tempting to call line() or plot() with x and y data being empty to set up the line with no contents, doing so will result in no line, and then R2014a will not notice it is working with an empty graphics object.
