In graphs, how high and how far right a point is describe its properties. Like the phase diagram of water: the further right you are, the higher the temperature, the further up you are, the higher the pressure. At each point, water would be in a certain state, which is plotted on the graph as colored areas.
Axes are markings that only help measure how hot and pressurized a certain point is. You are probably at around 100 kPa (atmospheric pressure) and 295 K (room temperature) so you experience liquid water. Even though the vertical axis is labeled “Pressure”, that does not mean pressure only exists on that line; same for the temperature axis. These meet at absolute zero in near-vacuum. Even though you pr But you might prefer axes at 0 °C (the left vertical red line) and 1 atm (the horizontal red line).
Graphs of temperature, voltage, air pressure, money etc. over time also use different units for the two axes.
Of course, some graphs do indeed use the same units, for example the cube-shaped RGB space has “1/255 of max subpixel brightness” units on all axes.
@ChaoticNeutralCzech don’t get it
