The same question is asked on the following link last year. ( http://www.mathworks.com/matlabcentral/answers/25488-brush-data-can-not-be-obtained )But no answers
h = brush;
set(h,'Enable','on','ActionPostCallback',@GetSelectedData);
what kind of a function should i write to retrieve 'GetSeletedData'?

Can you use below code to get selected x and y data ?
figure; p = plot(1:10) h = brush hBrushLine = findall(gca,'tag','Brushing'); set(h,'Enable','on','ActionPostCallback',{@GetSelectedData,hBrushLine});
function GetSelectedData(h,e,g)
brushedData = get(g, {'Xdata','Ydata'}); brushedIdx = ~isnan(brushedData{1});
brushedXData = brushedData{1}(brushedIdx) brushedYData = brushedData{2}(brushedIdx)
