There is no direct callback that gets executed when XLim/YLim property of the axes changes. But it is possible to create a callback function which will listen to the XLim/YLim property and get executed whenever XLim/YLim changes value.
In order to create a callback function, which gets fired when the XLim value changes, create an event listener using ADDLISTENER for the current axis. Then create a callback function in the same directory and assign it as the PostSet callback of the 'XLim' property.
The attached file, testCallback.m, and the callback function, Callbackfcn, illustrate this.

I am sorry for revocing such an old post, but I felt it fits so well with my issue.
I tested this callback function using R2017a.
The callback is activated when I manually change XLim.
But when I call plot(ax,...) the XLim property changes without activating the calback.
I can make a wrapper function for plot to activate the callback like this:
function myPlot(varargin)
line = plot(varargin{:});
set(line.Parent,'XLim',line.Parent.XLim);
end
but there is a lot of calls to plot that needs to be changed, is there a better way?
