Can I digitize a Line Graph automatically by Digitizer 7? I do not like to digitize a line graph manually because it is difficult to reproduce a line perfectly. I want to know a method to digitize a line (multi-points one time) automatically.

Thanks
Hearme

You could import a B&W image of the graph to a matrix and pick out the x and y coordinates of the line. It should be possible to write an LT or OC function which distinguishes the data plot from axes and labels.
