In order to demonstrate this, I've put up the files at
https://pub.ist.ac.at/~schloegl/20170518428373.matlab.eps.issue/
The script is here:
https://pub.ist.ac.at/~schloegl/20170518428373.matlab.eps.issue/example_eps_issue.m
The data is here:
https://pub.ist.ac.at/~schloegl/20170518428373.matlab.eps.issue/data.mat
I've tested this with fltk.
