_______________________________________________________
Details:
The FLTK/OpenGL plotting engine uses float values to represent data. Anything
plotted with values exceeding realmax ("single") cause strangely distorted
plots or no plots at all. Also, it is the range that is important, rather
than the individual data itself. Plotting from [-1e20, +1e20] will also cause
a problem. For log axes, of course, this restriction is lifted.
For the 3.8 release we need to add a bit of code to test the data and abort
the plot if it won't plot correctly. The warning message should mention two
solutions, 1) scaling the data or 2) reverting to gnuplot.
