# B.4 Plots with multiple axes

In gnuplot, a maximum of two horizontal and two vertical axes may be associated with each graph, placed in each case with one on either side of the plot. These are referred to as the `x` (bottom) and `x2` (top), or `y` (left) and `y2` (right) axes. This behaviour is reproduced in Pyxplot, and so the syntax

    set x2label 'Axis label'

works similarly in both programs. However, in Pyxplot the position of each axis may be set individually using syntax such as

    set axis x2 top

and furthermore up to 128 axes may be placed parallel to one another:

    set axis x127 top
    set x127label "This is axis number 127"

More details of how to configure axes can be found in Section 1.8.1.
