#### 3.15.1 axes

There are four possible sets of axes available; the keyword <axes> is used to select the axes for which a particular line should be scaled. ‘x1y1‘ refers to the axes on the bottom and left; ‘x2y2‘ to those on the top and right; ‘x1y2‘ to those on the bottom and right; and ‘x2y1‘ to those on the top and left. Ranges specified on the ‘plot‘ command apply only to the first set of axes (bottom left).
