[Octave-bug-tracker] [bug #40246] OpenGL should test data and abort plot if range > float range

[Rik]

Follow-up Comment #2, bug #40246 (project octave):

The tolerance should be an adjustable feature so we can tune it.

The problem for bug #33748 is not that realmax is exceeded but that the
precision is exceeded (only ~7 digits for single).  So, this might be
something else to test for.  In a quick and dirty test,


xmean = mean (x);
deltas = x .- xmean;
bad = any (deltas < eps (xmean));


But that would probably need some improving.
