echarts 饼状图

说明：这是我做项目时自己写的小例子，里面有冗余的参数。

开发环境 vs2012 asp.net mvc4  c#

1、显示效果

2、HTML代码

3、Home控制器的代码

  public JsonResult GetEarthPartList(string yearId)
        {
            EPTHZValueModel hzvalueModel = new EPTHZValueModel();
            hzvalueModel.gsEH = ;
            hzvalueModel.gxEH = ;
            hzvalueModel.plEH = ;
            hzvalueModel.wgEH = ;
            hzvalueModel.wjEH = ;
            hzvalueModel.ysEH = ;
            hzvalueModel.zjEH = ;

            decimal[] myArray = new decimal[] { hzvalueModel.gsEH, hzvalueModel.gxEH, hzvalueModel.wgEH, hzvalueModel.wjEH, hzvalueModel.plEH, hzvalueModel.ysEH, hzvalueModel.zjEH };
            hzvalueModel.totalEH = MaxO(myArray);
            return Json(hzvalueModel, JsonRequestBehavior.DenyGet);
        }

    private decimal MaxO(decimal[] myList)
        {
            decimal a = , b = ;
            for (int i = ; i < myList.Length; i++)
            {
                a = b - myList[i];
                if (a < )
                {
                    b = myList[i];
                }
            }
            return b;
        }

   public class EPTHZValueModel
    {
        public System.Decimal totalEH { get; set; }
        public System.Decimal wgEH { get; set; }
        public System.Decimal wjEH { get; set; }
        public System.Decimal plEH { get; set; }
        public System.Decimal gsEH { get; set; }
