I absolutely agree, but I don't think we need this for the 3.4.1 release.
I thought the switchover from gnuplot to FLTK as the default was expected
only before the next major release, i.e., 3.6. Also, I'm not sure that
this has a simple fix. Do we just need to add listeners on the
xdata,ydata,zdata channels and warn if values exceed 1e38?
