07 Oct 2011 Figure Digitizer Digiize a curve in a figure to get the data coordinates. Author: Hongxue Cai KYAW, KYAW

Dear Hongxue Cai,

Thank you for your contribution and I would like to know how to use your GUI funciton since I am looking for a way to get the x and y coordinates of edge detected images(*.jpg).

Since I was new in this task and pls advise me. I am looking forward to hearing from you good news soon.

Thanks and best regards

Here's how a Swiss guy, Dominique Lovy solved this:

It works really fine on any Windows machine.

Agree with "ming s", there is an error with log plots. The fix provided works for me if I use a slightly different script (in this example, I calculate d differently than ming s:
    c = (log10(handles.y2v) - log10(handles.y1v))/(handles.y2 - handles.y1);
    d = log10(handles.y2v) - handles.y2*c;
    yy = c*handles.y + d;
    yy=10.^yy;

It's a very good initiative but a precision of two or so digits is not good enough for my purposes, and I would think this goes for many other users too.
