I tried hard to export. Actually, I had exported

Answer 1

You can export x and y vectors from a figure (assuming the figure is a 2D plot for a single data set) by:

h = plot(1:10);
xVec = get(h,'XData');
yVec = get(h,'YData');

If you dont have the handle but the figure is open, then you can use gcf, gca as the handle for the current active figure or axis.

If you have multiple data sets (lines) in the figure you can get all of the associated data by:

lines = findobj(h, 'Type', 'line'); //h is the handle to the figure
nlines = length(lines);
points = cell(nlines,2);
for i = 1:nlines
    points{i,1} = get(lines(i),'XData');
    points{i,2} = get(lines(i),'YData');
end
