The underlying issue is that because of bug #33748 and bug #40246 I need to
revert to gnuplot. Now gnuplot also bugs out on me. 
Rescaling before handing off to fltk/OpenGL is quite cumbersome as we'd need
to patch all code (many of which is Matlab code still used in Matlab)
invoking plotting. That's hundreds of functions to process....
