[DevExpress]ChartControl之滚动条示例

关键代码：

        /// 设置ChartControl滚动条【默认X,Y轴都出现】
        /// </summary>
        /// <param name="chart">ChartControl</param>

        /// <param name="borderColor">滚动条边框颜色</param>
        /// <param name="barThickness">滚动条宽度</param>
        public static ScrollBarOptions SetScrollBar(this ChartControl chart, Color backColor, Color barColor, Color borderColor, int barThickness)
        {
