Let's say we have a graphic which consinst of x axis and y axis, but the shown lines in graphic are gathered from many experimental data's and we can't reach to those informations. So we are left with only graphic. To make situation worse we just have pdf version of the graphic.
In this case, how can we make a program which will read values from this graphic?
The question might be awkward. Im die-hard newbie in programming. I just wanted to ask and see what you guys would think about this.
