## base-line-drawn

Arguments: bar-chart-view

Returns the value of the base-line-drawn property of a `bar-chart-view`. The value may be set at creation time by passing the `base-line-drawn` initarg, or any time later by calling (setf base-line-drawn).

A boolean value indicating whether a line is drawn at the base-value of a `bar-chart-view` in a `chart-widget`. The default value is `nil`.

When true, a line is drawn across the body of the chart-widget parallel to the item-axis and at the base-value of the `bar-chart-view`. The line's thickness will be the base-line-width of the bar-chart-view and its color will be the base-line-color.

If the base-value is equal to the range-bottom or range-top of the value-axis, or if the base-value is outside that range, then the base line is never drawn.

See `chart-widget` and also cg-chart-widget.htm.
