On appeal, what is the test for assuming a judge considered all available evidence in making a ruling?

On appeal, we presume the trial court's judgment is correct, and thus "[a]ll intendments and presumptions are indulged to support it on matters as to which the record is silent, and error must be affirmatively shown." (Denham v. Superior Court (1970) 2 Cal.3d 557, 564,) Thus, we are obligated to assume the court did consider all available evidence in making its ruling, unless the record affirmatively demonstrates otherwise. There is no such affirmative demonstration here.
