Hi Andrew,
Finally, do you know how I can preserve the axis limits after zooming?
thanks

Please anser my question. Keeping the limits and zooming is a contradiction. Therefore you cannot do both.

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));

Hi Jan,
I have could resolve the issue.
I had the answer in frot of me...
The solution has been put the keeplimits arg when I call datetick function.
Sometimes, I think that when you are thinking that you have a big problem, really it's not true because you have a very simple solution for this.
However, thank you for trying to help me.
regards

If I understand your question, you can do something like the following. Make your first plot, for example
plot(1:10)
Zoom in, and then save the values of axis:
v = axis;
Finally, make your next plot and set the axis values.
plot(3:5)
axis(v)
