One trick is to use HGLOAD

For example, as explained here

http://stackoverflow.com/questions/2976505/how-can-i-extract-data-from-a-fig-file-in-matlab

Try hgload and then poke around the graphics handle structure it returns. For example, if you plot and save the following:

x=0:.01:10; y=sin(x); h=plot(x,y); saveas(h,'testfigure.fig'); Clear your workspace, and open the saved figure using hgload:

clear close all h=hgload('testfigure.fig'); You can inspect the figure's handle h by calling

get(h) Or delve further into the axes/titles/legends by calling

ch=get(h,'Children'); If you're using the code in my example, you should only have one child for the figure, which will be the axes. Call the children of the axes, and you should have one line.

l=get(ch,'Children'); Next, call the 'Xdata' and 'Ydata' fields of the line, and you have your original data.

x=get(l,'Xdata'); y=get(l,'Ydata'); If you have a more complicated figure than just axes, it gets a little tougher. You'll need to explore each child to determine if it's the plot you wanted to extract data from.

“everything that is living can be understood in terms of the jiggling and wiggling of atoms”.

and now, we want to watch atoms jiggling and wiggling.

X-rays, electrons, fluorescence light, the advances of photon sciences, together with computational modeling, are making this happen.
