Arguments: plot-widget
Returns the value of the x-axis property of a plot-widget
. The value may be set at creation
time by passing the x-axis initarg to
make-instance when creating a
plot-widget, or any time later by calling (setf x-axis).
The x-axis of a plot-widget
is the primary horizontal axis of the widget, and always lies along
the bottom side of the plot. If a secondary horizontal axis is desired
along the top side of a plot, then use the x-axis-2 property for that.
The value of the x-axis
property should be an instance of the plot-value-axis
class, and holds properties that
determine how the axis is drawn and the range of values that it
displays. The properties are inherited from the value-axis
and chart-axis
classes.
The value of this property will always be a plot-value-axis
instance. If you do not pass a
plot-value-axis
instance as
the value of the x-axis initarg when creating a
plot-widget
, then a default
instance is created automatically.
If there are multiple chart objects (see chart-objects), then some of the objects may use this axis for their x coordinates while others use the x-axis-2 axis.
