Get values represented in a figure (GUIDE)

Hello everyone,
I am working in a GUIDE which plots two figures
One of them is a simple data representation (figure1) and the other is the result of one algorithm(figure 2)
My idea is make something interactive to zoom in the data representation and automatically perform the algorithm refreshing the figure 2
Im reading about linkprop but I dont know how to get handle with the data represented just in the window (zoomed) of the figure 1.
Perhaps there is other approach easier
Thanks in advance!

founded! (more or less)
get(handles.axes1,'XLim')
get(handles.axes1,'YLim')

this get the limits of the are represented
then u only have to filter, for example
rangeY=get(handles.axes1,'YLim'); %obtain limits of y values in time space plot
rangeX=get(handles.axes1,'XLim'); %obtain limits of x values in time space plot
sourcedata = getappdata(0,'sourcedata'); %obatin original data saved before on root 0
rangedDATAprevious = source data((sourcedata(:,1)>=rangeX(1) & sourcedata(:,1)<=rangeX(2)),:);
rangedDATA = rangedDATApreivous((rangedDATAprevious(:,2)>=rangeY(1) & rangedDATApprevious(:,2)<=rangeY(2)),:);
