This curious fact was first noticed back in the early s by two astronomers, American Henry Norris Russell and Dane Ejnar Hertzsprung. As a result, this sort of graph is called a Hertzsprung-Russell diagram, or "HR diagram" for short. Norris and Russell called the diagonal strip along which most stars fall the main sequence.

The H-R diagram is a scatter graph of stars – a plot of stellar absolute magnitude or luminosity versus surface temperature or stellar classification. Stages of stellar evolution occupy specific regions on the H-R diagram and exhibit similar properties.

The Hertzsprung-Russell diagram (or HR diagram) is constructed in logarithmic coordinates. In this graphic construction, each star is a point marked on the ordinate by its brightness (luminosity or absolute magnitude) and on the abscissa by its spectral type (or surface temperature).

The Hertzsprung-Russell (HR) diagram is a plot of luminosity (total power output) against surface temperature, both on log scales. Since neither luminosity nor surface temperature is a directly observed quantity, real plots tend to use observable quantities that are related to luminosity and temperature.
