How can I get the minimum and maximum value of the xaxis when I zoom in on a plot?

 Is it possible to define a callback when I zoom in on the plot and get the minimum and maximum x values from the plot? Kindly request you to give an example.

Thanks in Advance.

Have you looked at the xlim() function?

I got the answer. I used the ActionPostCallback Function

function ZoomTag_OnCallback(hObject, eventdata, handles)

h = zoom(handles.axes1); set(h,'ActionPostCallback',@mypostcallback); set(h,'Enable','on');

%Occurs after mouse button up for zoom function function mypostcallback(obj,evd) global newLim; newLim = get(evd.Axes,'XLim');

Yep, like I thought. But if evd.Axes or handles.axes1 is the current axes, you can simply to

newLim = xlim();

which is simpler. If it's not the current axes, you can do

newLim = xlim(handles.axes1);
