If you mean a Hertzsprung-Russell Diagram, which plots stars color, temperature, and absolute magnitude (see related link), then it looks like color and spectral class (temperature) are plotted on horizontal, and Absolute Magnitude/Lumenoscity are plotted on the vertical.
The HR diagram has the star's temperature along the horizontal axis and the absolute magnitude (brightness) along the vertical axis. Each star is represented by a single dot. Higher temperature is usually associated with more brightness so many stars lie on or near a line on the diagram called the Main Sequence. Red giant stars are found on the upper right hand quarter because they are relatively cool but still very bright.
its located somewhere
The HR diagram does not reference stars on their way to the main sequence, only during or after.
The temperature and luminosity of stars.
On the main sequence.
Main sequence
The two ways are by their surface temperature (spectrum) and by their absolute magnitude (intrinsic brightness). The HR diagram has spectrum along the horizontal axis and absolute magnitude along the vertical axis. Each star occupies a point in the HR diagram.
The temperature is displayed along the horizontal axis while the vertical axis is the star's absolute magnitude. So the HR diagram is a scatter diagram relating temperature and brightness, and eah star occupies one point.

That is called the Hertzsprung-Russell or HR diagram and each star occupies a point. The horizontal axis is temperature and the vertical axis is the absolute magnitude.
The x axis is the temperature *Kelvin. While the y axis is the luminosity of the star.
That is called the HR diagram (Hertzsprung Russell) and the temperature is along the horizontal axis while the vertical axis is the star's absolute magnitude. Each star has a fixed point in this diagram, and it shows that most stars belong in a broad band on the left called the Main Sequence.
On the HR diagram each star occupies a single point, depending on its surface temperature (horizontal) and its absolute magnitude (vertical).
The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed
The main reason that the HR Diagram is so useful and important to scientists is, you can tell the size of the star by plotting it on the HR Diagram. The different sizes of stars form a pattern on the HR diagram.
The HR diagram contains only stars - so everywhere.
Of course they are on the HR diagram. They are simply not on the main sequence.
