              Chart 控件，功能强大，可以绘制柱状图，折线图，波形图，饼状图，大大简化了对图的开发与定制。
              Chart控件的相关概念：

              ChartArea，表示图表区域，一个Chart可以绘制多个ChartArea，重叠在一起。
              Series ，表示数据序列，每个ChartArea可以有多个数据线。即，Series属于ChartArea.
              AxisX,AxisY,表示主坐标轴，每一个ChartArea都有对应的坐标轴，包括主坐标轴，辅坐标轴
              Queue集合，表示先进先出的集合。
              主要有两个方法：

              Dequeue() 表示移除并返回位于 System.Collections.Generic.Queue<T> 开始处的对象。
              Enqueue() 表示将对象添加到 System.Collections.Generic.Queue<T> 的结尾处。
              Timer ，定时器，定时之行相应的功能，更新数据，刷新图表。
