What's the Word for a Biography that's Intended for Praise? Halography.

I remember reading an article on the movie Patton that suggested that Omar Bradley’s participation was his attempt to portray Patton in as positive a light as possible. I thought the word used to describe such a biography was “halography”, but it isn’t in the dictionary. Does anyone know the correct word?

Hagiography.

Thank you!

You’re very welcome!
