      Before this update, a rounding error caused metrics charts to display gaps even when the underlying data was continuous. With this release, the rounding error has been corrected, ensuring that charts display without gaps when the data is complete. (link:https://issues.redhat.com/browse/OCPBUGS-65958[OCPBUGS-65958])
