This statement is true, because the Hertzsprung-Russell diagrams are graphs of luminosity as a function of temperature, or of magnitude or absolute magnitude as a function of spectral class.
What is the HR diagram for explain its function?
The H-R diagram can be used to define different types of stars and to match theoretical predictions of stellar evolution with observations of real stars using computer models.
In this case, this statement is true, because the Hertzsprung-Russell diagrams are graphs of luminosity as a function of temperature, or of magnitude or absolute magnitude as a function of spectral class.
