A planet's axis is the imaginary line that the planet rotates around, like spinning top.

The scatter plot of the relationship between a star's temperature and luminosity is represented by the Hertzsprung-Russell diagram. In a standard H-R diagram the horizontal axis shows the [surface] temperature, increasing from right to left, while the vertical axis shows luminosity increasing from bottom to top. When both axis are on a logarithmic scale, the main sequence stars from a diagonal belt stretching from top right (very hot and very luminous) to bottom left (not so hot and not so luminous).

top
When a planet spins on its axis it is said to rotate. (Think of a top.)
rotate - to revolve round a centre or axis
on the top of planet earth there is the north pole, on top of that is the northern most axis of the Earth, the axis may be cold or hot depending on the axis' current tilt.
The Earth's top and bottom are defined by the North and South poles, respectively. The concept of top and bottom is based on human perception, as Earth is a sphere with no true top or bottom in space.

The y axis always runs vertically.
