"A phase diagram is a graph of pressure versus temperature that shows in which phase a substance exists under different condition of temperature and pressure" -Glencoe Chemistry Book
To draw a phase diagram for nitrogen, plot temperature on the y-axis and pressure on the x-axis. Include regions for solid, liquid, and gas phases. Mark the triple point where all phases coexist and the critical point where liquid and gas phases merge. Connect the regions with phase boundaries to create the full diagram.
This only occurs at a specific point on the phase diagram of a substance called the "triple point." This point corresponds to a certain pressure and temperature for an individual substance, since these are the axis values for a phase diagram.
The x axis is the horizontal axis. The y axis is the vertical axis.
The vertical axis is the y-axis. The horizontal axis is the x-axis.
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.

The y axis is vertical and the x axis is horizontal.
The y-axis is vertical and the x-axis is horizontal.
The vertical axis is a reference axis usually denoted as y-axis in Cartesian co-ordinate system. It can be said that a vertical axis is the axis perpendicular to a reference horizontal surface.
