nonsingular

MinorSymLogLocator.nonsingular(v0, v1)

Adjust a range as needed to avoid singularities.

This method gets called during autoscaling, with (v0, v1) set to the data limits on the axes if the axes contains any data, or (-inf, +inf) if not.

• If v0 == v1 (possibly up to some floating point slop), this method returns an expanded interval around this value.

• If (v0, v1) == (-inf, +inf), this method returns appropriate default view limits.

• Otherwise, (v0, v1) is returned without modification.
