Open and draw multiple charts (.fig files) into 1 chart

Hey!

There is a possibility to open a previously saved multiple *.fig files, but with concrete names, i.e. spec303, spec 296, and draw them into 1 chart?

1. I wrote a script which effectively generate normalize plots, i.e. from spec20, ... via spec88, spec89... to spec500 etc.
2. Then, I saved them as *fig. files.
3. I would like to open a concrete *.fig files (i.e. only 296, 303 etc) and compare them but in one chart. (all those concrete files have the same range of x axis).

Thanks in advance for any tips.
