bar-width

Arguments: bar-chart-view

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

The width, measured in pixels, of the bars of a bar-chart-view in a chart-widget. The value should be a positive integer. The default value is 12.

When there are multiple side-by-side bars for each chart item (which is when there are multiple chart-objects and the values-are-stacked property is nil), this is the width of a single bar rather than the width of the group of side-by-side bars.

If fit-chart-items is true, then this value will be scaled proportionally with other sizing properties to make all data fit in view.

See also bar-spacing.
