(by hand :)). I currrently use Grapher for digitizing. If you don't hav
e this software, try searching digitize in google to see whether there's
some free ware.
If using matlab, you can use "imread" to read the image into a matrix an
d write a program to find the profile by detecting the color change in t
he image. If the plot only have a single curve, it is better to scan the
plot into Black/White form; and then you will s
