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);
