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.
