Scientific research needs , I often draw many pictures , In general, I will use these pictures as fig Format preservation ( It is very convenient for the reviewer to change the drawing ), In this way, it can be well restored when there are many data thieves and it is difficult to organize .

For example, the following pictures

After a while , I don't know where the original data went for a long time , At this time, you can use the following code from fig Restore data from file

open('untitled2.fig')
lh = findall(gca,'type','line')
y = get(lh, 'ydata')

Among them y Is the restored data , then plot Just modify it again .
