icon-line-length

Arguments: chart-legend

Returns the value of the icon-line-length property of a chart-legend. The value may be set at creation time by passing the icon-line-length initarg, or any time later by calling (setf icon-line-length).

The length, measured in pixels, of the line for each chart object in the chart-legend of a chart-widget. The value should be a positive integer. The default value is 24.

Sample lines will be drawn in the legend only when the chart-view of the chart-widget is :line to display a line-graph-view. Other attributes of the sample line will be taken from various line-graph-view properties. The icon-line-length should be large enough to make the style of the line clear, especially when the sample includes an icon due to the draw-icons property of the line-graph-view being true.

This property is used only when the draw-legend property of the chart-widget is true
