compareDomainValueToViewport method
Tests whether the given domainValue
is within the axis' range.
Returns < 0 if the domainValue
would plot before the viewport, 0 if it
would plot within the viewport and > 0 if it would plot beyond the
viewport of the axis.
Implementation
@override
int compareDomainValueToViewport(num domainValue) {
final dataExtent = _viewportSettings.domainExtent ?? _domainInfo.extent;
return dataExtent.compareValue(domainValue);
}
