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')

Not sure how that does it. All that does is to get the range of the X and Y axes of axes1. It doesn't get any handle to any data you plotted. But whatever.....

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)),:);

plot(rangedDATA)
