## x-axis

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.

See also x-axis-2, y-axis, y-axis-2, and `plot-widget`.
