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

[Markus Mützel]

Follow-up Comment #13, bug #58956 (project octave):

Maybe we could use some logic like this in the C++ code (written in Octave for
simplicity):

Z = [707106781186.04761, 707106781187.04761];

if sum(Z)*eps('single')*5 > diff(Z)*100
  Znew = sum(Z)/2 + sum(Z)*eps('single')*5 * [-1,1];  % 5 is an arbitrary
value here. Choose something that works
else
  Znew = sum(Z)/2 + diff(Z)*100 * [-1,1];  % close to what we currently have
for bug #54551 without the ´min´ and ´max´
end

span = diff(single(Znew))


If I got this right, ´span´ should always be greater than 0 after that for
any Z with Z(1)<Z(2).
I'm still struggling to understand why the ´min´ and ´max´ that we
currently have are needed.
