The set axis command also accepts the following keywords alongside the positional keywords listed above, which specify how the axis should appear:
arrow – Specifies that an arrowhead should be drawn on the right/top end of the axis. [Not default].
atzero – Specifies that rather than being placed along an edge of the plot, the axis should mark the lines where the perpendicular axes x1, y1 and/or z1 are zero. [Not default].
automirrored – Specifies that an automatic decision should be made between the behaviour of mirrored and nomirrored. If there are no axes on the opposite side of the graph, a mirror axis is produced. If there are already axes on the opposite side of the graph, no mirror axis is produced. [Default].
fullmirrored – Similar to mirrored. Specifies that this axis should have a corresponding twin placed on the opposite side of the graph with mirroring ticks and labelling. [Not default; see automirrored].
invisible – Specifies that the axis should not be drawn; data can still be plotted against it, but the axis is unseen. See Example 1.11.2 for a plot where all of the axes are invisible.
linked – Specifies that the axis should be linked to another axis; see Section 1.8.9.
mirrored – Specifies that this axis should have a corresponding twin placed on the opposite side of the graph with mirroring ticks but with no labels on the ticks. [Not default; see automirrored].
noarrow – Specifies that no arrowheads should be drawn on the ends of the axis. [Default].
nomirrored – Specifies that this axis should not have any corresponding twins. [Not default; see automirrored].
notatzero – Opposite of atzero; the axis should be placed along an edge of the plot. [Default].
notlinked – Specifies that the axis should no longer be linked to any other; see Section 1.8.9. [Default].
reversearrow – Specifies that an arrowhead should be drawn on the left/bottom end of the axis. [Not default].
twowayarrow – Specifies that arrowheads should be drawn on both ends of the axis. [Not default].
visible – Specifies that the axis should be displayed; opposite of invisible. [Default].
The following simple examples demonstrate the use of some of these configuration options:
set axis x atzero twoway set axis y atzero twoway plot [-2:8][-10:10]
set axis x atzero arrow set axis y atzero twoway plot [0:10][-10:10]
set axis x notatzero arrow nomirror set axis y notatzero arrow nomirror plot [0:10][0:20]
