You need to access XData and YData property, for example:
h = plot(1:10);
get(h,'XData')
get(h,'YData')
Here is a handy tool to find out the handle graphics properties

What if I don't have access to h? and just have a plot in front of me that pops up due to some code running?

If it just recently popped up, and you can run some code to get to it before focus switches to some other figure, then you can use gca or gcf for the handle.
