Any 2D-plot can be exported as a *.txt file and can be imported to matlab.
while you're viewing the plot go to post processing tab and then import/export key next you'll be able to get the text of your plot, if you choose the plot data (ASCII) bottom.
then you'll be able to do as you wish with it in matlab.
