[Octave-bug-tracker] [bug #58956] Empty plot for certain xlim / ylim settings

[Markus Mützel]

Follow-up Comment #31, bug #58956 (project octave):

At least on the system that I could test, it *does* make a difference. Afaict,
we are using double precision interfaces of the OpenGL function (e.g.,
`glMultMatrixd` or `glVertex3d`). I'd guess that the transformations are still
done in double precision. The result is converted to single precision before
it is rendered.
So taking your example from comment #28, it looks like the effective code
would look more like the following with your patch:

t = now-1:(1/1440):now;
x = -cos(2*pi*t) + rand(size(t))/10;
t = single(t - fix(now));
plot(t,x)
