Open the figure:

h = findobj(gca,'Type','line')
x=get(h,'Xdata') ;
y=get(h,'Ydata') ;

(x,y) is your required data.

what if you want to extract data of two lines ?

@seshu kumar vandrangi

h = findobj(gca,'Type','line')
x1=get(h(1),'Xdata') ;
y1=get(h(1),'Ydata') ;

x2=get(h(2),'Xdata') ;
y2=get(h(2),'Ydata') ;

Hi, how can I extract data andd save as mat file from a figure which has 3 subplots, like this:

[Zack Trahem]

let say i have y values and need to find the corresponding location, can we find the unspecified location? As an example on figure i want to find the time of the 68.5 m/s ??

If you want to get the values of unknown points from the figure and have to use in code then this could be helpful.

delete 2.fig;
savefig('2.fig');
open('2.fig');
h = gcf; %current figure handle
axesObjs = get(h, 'Children');  %axes handles
dataObjs = get(axesObjs, 'Children'); %handles t
xdata = get(dataObjs, 'XData'); 
ydata = get(dataObjs, 'YData');
