We use probplot and qqplot to plot differece between normal and data distribution. Is there a way to get the data of the plot from it? Thank you!

If you want the display limits, get() the XLim and YLim properties from the axes containing the plots. If you want coordinate information, findobj() the "line" or (for scattergrams with sufficiently many points) "patch" objects and get() their XData and YData properties.
For example,
xdhandles = findobj(gcf, '-prop', 'XData');
xydata = cell(length(xdhandles, 2);
for K = 1 : length(xdhandles)
h = xdhandles(K);
xydata{K, 1} = get(h, 'XData');
xydata{K, 2} = get(h, 'YData');
end
