袁氏报表用代码画一个饼图

先要建一个ReportService.aspx 代码如下:

XDesigner.Report.ReportHtmlBuilder hb  =   this .Session[ " htmlbuilder " ]  as  XDesigner.Report.ReportHtmlBuilder;
         if  (hb  ==   null )
             return ;

         if  ( this .Request.QueryString[ " imageindex " ]  !=   null )
         {
            System.Drawing.Imaging.ImageFormat f = System.Drawing.Imaging.ImageFormat.Png;

            string imagType = this.Request.QueryString["imagetype"];
            if (imagType == "jpg")
                f = ImageFormat.Jpeg;

            hb.SaveReportImage(
                Convert.ToInt32(this.Request.QueryString["imageindex"]),
                this.Response.OutputStream,
                f);
            return;
        }

         if  ( this .Request.QueryString[ " out " ]  ==   " doc " )
         {
            // Output MS Word 2000 document
            hb.SaveWordDocument(this.Response.OutputStream);
            this.Response.ContentType = "application/msword";
            //this.Response.AppendHeader("Content-Disposition","attachment;filename=" + System.Web.HttpUtility.UrlEncode( hb.Title ) + ".doc");
        }
         else   if  ( this .Request.QueryString[ " out " ]  ==   " xls " )
         {
            // Output MS Excel2000 document
            hb.SaveExcelDocument(this.Response.OutputStream);
            this.Response.ContentType = "application/vnd.ms-excel";
            //this.Response.AppendHeader("Content-Disposition","attachment;filename=" + System.Web.HttpUtility.UrlEncode( hb.Title ) + ".xls");
        }
         else   if  ( this .Request.QueryString[ " out " ]  ==   " pdf " )
         {
            hb.SavePDFDocument(this.Response.OutputStream);
            this.Response.ContentType = "application/pdf";
        }
         else
            hb.Save( this .Response.Output);

再建一个页面画大饼咯:

// 先增一个报表
        DesignReportDocument doc  =   new  DesignReportDocument();
        doc.Title  =   " 动态报表 " ;

         // Lable
        DesignReportLabel lbl  =  doc.CreateLabelElement();
        lbl.Text  =   " 动态报表演示 " ;
        lbl.TextColor  =  System.Drawing.Color.Yellow;
        lbl.Font  =   new  Font( " 宋体 " ,  20 , System.Drawing.FontStyle.Bold  |  System.Drawing.FontStyle.Italic);
        lbl.Align  =  StringAlignment.Center;
        lbl.PrintDockStyle  =  PrintDockStyle.Top;
        lbl.Height  =   120 ;
        lbl.Border.BackColor  =  Color.SkyBlue;
        doc.Add(lbl);

         // 一个大饼
        DesignReportPie pie  =  doc.CreatePieElement();
        pie.Bounds  =   new  Rectangle( 169 ,  775 ,  1363 ,  954 );
        pie.Thickness  =   60 ;
        pie.BorderWidth  =   1 ;
        pie.LeftBorder  =   false ;
        pie.TopBorder  =   false ;
        pie.RightBorder  =   false ;
        pie.BottomBorder  =   false ;
        doc.Add(pie);

         // 增加列
         for  ( int  i  =   1 ; i  <   5 ; i ++ )
         {
            DesignReportPieItem pieItem = doc.CreatePieItemElement();
            pieItem.ID = "pieItem" + i;
            pieItem.Value = i.ToString();
            pieItem.Text = i.ToString() + "_" + i.ToString();
            pieItem.FillColor = System.Drawing.Color.FromArgb((i * 1000) % 255, (i * 100) % 255, (i * 10) % 255);
            //pieItem.BackColor = System.Drawing.Color.FromArgb(255, 255, (i * 100) % 255);
            pie.AppendChild(pieItem);
        }

        DesignReportLabelList reportpietext1  =  doc.CreateLabelListElement();
        doc.AppendChild(reportpietext1);
        reportpietext1.ID  =   " reportpietext1 " ;
        reportpietext1.Bounds  =   new  System.Drawing.Rectangle( 215 ,  24 ,  1175 ,  731 );
        reportpietext1.BorderWidth  =   1 ;
        reportpietext1.ItemSpacing  =   30 ;
        reportpietext1.ItemHeight  =   50 ;
        reportpietext1.Font  =   new  System.Drawing.Font( " 宋体 " , 9F, System.Drawing.FontStyle.Bold);
        reportpietext1.BarSize  =   60 ;

        XDesigner.Report.ReportBuilder rb  =   new  ReportBuilder();
        rb.LoadReport(doc);

        XDesigner.Report.ReportHtmlBuilder hb  =  rb.CreateHtmlBuilder();
        hb.ImgSrcFormatString  =   " reportservice.aspx?imageindex={0} " ;
        hb.Refresh();
        hb.ContentEncoding  =   this .Response.ContentEncoding;

         this .Session[ " htmlbuilder " ]  =  hb;
        hb.Save( this .Response.Output);
