`axis(x)`

Inputs | |

`x` |
A vector of four real numbers or a string. |

This function overrides the default mechanism for setting the limits on the current plot. If the input is the string

`'square'`

, limits are forced to be such
that one unit along the `x-axis`

is assigned the same number of pixels
as a unit along the `y-axis`

. If
the input is an array of four numbers,
the function sets the limits of the x-axis to be `x[1]`

and
`x[2]`

, and those of the y-axis to be `x[3]`

and `x[4]`

.
