I made this code bug-for-bug compatible because you asked for it to function exactly the same as your R2014 code. In your code, the "axis equal" overrode the xlim([-10,1000]) and ylim([-10,1000]) giving you limits of -1000 to +1000. The axis equal also set the xlimmode and ylimmode to auto which is why if you just remove the drawmode parameter with your code you would get the unexpected scrolling x axis. The effect of "axis equal" on the xlim and ylim in R2014a can depend upon the commands that follow before the object is rendered and upon the figure position, so I force the object to render before turning off automatic axis limits so that the x axis limits are set to [-640.286298568507, 640.286298568507] in a bug-for-bug compatible way.
I would suggest that you revise the code to do what your code appears to want to do, not what your current code does.
box=[0 20 20 0; 0 0 20 20];
h.box= patch(0,0,'b');
xlim([-10,1000]); ylim([-10,1000]);
hold on;
for i = 1: 1000
xb=box+i;
set(h.box, 'xdata', xb(1,:), 'ydata', xb(2,:))
drawnow;
end
Without the "axis equal" after you have already set your xlim and ylim, the limits become exactly what you set and remain that way because xlim() and ylim() set xlimmode and ylimmode to 'manual' (no need to force them back to manual after "axis equal" has reset them if you skip the "axis equal")
