## draw-lines

Arguments: object

draw-lines is a property of the `outline` and `dropping-outline` classes. It is also a property of `line-drawing-view`s, which are associated with the `chart-or-plot` widgets.

### For outline widgets

Returns the value of the draw-lines property of object. This property determines whether or not an outline control will have long vertical and short horizontal lines graphically depicting the hierarchy of the outline.

### For chart-or-plot widgets

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

A boolean value indicating whether graph lines are drawn for a `line-drawing-view` in a `chart-or-plot`. The default value is `t`.

Either this property or draw-icons (or both) should be true, because otherwise nothing would be drawn for the data values.

For a `chart-widget`, this property and other `line-drawing-view` properties are used only when the chart-view property of the `chart-widget` is `:line` to display the `line-graph-view`.

See also line-colors, line-widths, line-dashings, and span-missing-items.
