    调用需要提供数据哦 用法如下:

            {
                MSChartHelpe cxh = new MSChartHelpe();
                MemoryStream ms = new MemoryStream();  
                string taskreport = @"。。。。。。";
                XDocument taskreportxd = XDocument.Load(taskreport);
                if (taskreportxd == null )
                {
                    getDefaultImg(cxh);
                    return;
                }
    。。。。。。。。 
                var DataDict = new Dictionary<stringdouble>(); 
    。。。。。。。
     
                ms = cxh.GetColumnImg(DataDict,  "",  "","","",500,400,50);
                Context.Response.Clear();
                Context.Response.ContentType = "image/jpeg";
                Context.Response.AddHeader("Cache-Control""max-age=3600");
                ms.WriteTo(Context.Response.OutputStream);
            }
            private void getDefaultImg(MSChartHelpe cxh)
            {
                MemoryStream ms = cxh.GetDefaultImg();
                Response.Clear();
