        // updating the appropriate dynamic range column and having the
        // TaskPane read the column and redraw the graph.  This takes a while,
        // however, and it slows down the responsivenees of the RangeTrackBar
        // control the user is changing.
        //
        // Instead, use a timer to delay the handling of the
        // SelectedRangeChanged event, and reset the timer as more such events
        // come in.  This allows the RangeTrackBar control to update more
        // quickly and postpones the redrawing of the graph until the user
        // pauses or stops changing the RangeTrackBar control.
