import the data in figure

Hello,

I plotted a figure file (*.fig) from the matrix data file using Matlab. But, I deleted the matrix file.
So, I want to import the data from figure. Then, how can I import the data in figure?

Thanks.

For example:


x = 1:10;
y = x.^2;
plot(x,y)
clear x y % x and y are lost.
ch = get(gca,'ch');
x = get(ch,'xd')
y = get(ch,'yd')

Thanks a lot for your help.

It works nice.

BUT, what if you zoom in a fig and then want to get [X,Y] pairs from zoomed fig/axes?

Zooming into a figure or axes doesn't change the coordinates of the points
in the data space. It does change them in the pixel space, but that's a
separate question. Are the data space coordinates what you're after, the
pixel space coordinates, or something else?
