scroll-on-drag-factor

Arguments: chart-widget

Returns the value of the scroll-on-drag-factor property of a chart-widget. The value may be set at creation time by passing the :scroll-on-drag-factor initarg, or any time later by calling (setf scroll-on-drag-factor).

scroll-on-drag-factor is the number of pixels by which a chart-widget will scroll along its item-axis for each pixel of mouse movement during a drag scroll. The value should be a positive real number. The default value is 3, to cause the chart to scroll three times as far as the mouse moves.

This property is used only when the scroll-on-drag property is true.

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