edit data in a figure

Dear all,

I currently have a problem that I used radii instead of diameter in figure plot. How can I change back to diameter, but I don't want to rerun the simulation because it takes me plenty of time.

For example, I have

x=1:10;

y=2:11;

u=20:30;

v=21:31;

plot(x,y,'r-',u,v,'b-');

Now, I would like to have x=2*x. How can I do it ? Thank you.

I think you don't have the simulation data, that's why it is a problem for you. Is it so?

Yes, that's it. It is funny to comment on something posted 4 years ago. That was a pore constriction size graph. The simulation took me few days to run (seriously), and I saved only figures not the data. All I did was extracting data from the graph. So easy. Laughing on my stupidity.
