如何绘制flash3D饼状图

                                                       《如何绘制flash3D图》

  在常见的管理类软件中，经常需要绘制简单明了的树状图，饼状图，都是为了方便统计，让客户对数据一目了然，那么首先看看如何绘制flash 3D饼状图

  1.首先看看参数

  /// <summary>
        /// 获得绘制Flash3D饼图图表的代码
        /// </summary>
        /// <param name="dt">数据表</param>
        /// <param name="caption">标题</param>
        /// <param name="lableColumnInDataTableIndex">标签列在数据表中的索引号</param>
        /// <param name="valueColumnInDataTableIndex">值列在数据表中的索引号</param>
        /// <param name="applicationPath">应用程序路径</param>
        /// <param name="chartWidth">宽度</param>
        /// <param name="chartHeight">高度</param>
        /// <returns></returns>

 我们传入的数Datatable，然后是标题，标签列在数据表的索引号，值列的索引号，应用程序的路径，图像的宽度和高度

   public static string Get3DPieChartCode(DataTable dt, string caption, int lableColumnInDataTableIndex, int valueColumnInDataTableIndex, string applicationPath, int chartWidth, int chartHeight)
        {
            StringBuilder sb = new StringBuilder();
            sb.AppendFormat(@"<chart caption='{0}' palette='4' decimals='0' enableSmartLabels='1' enableRotation='0'  bgAlpha='40,100' bgRatio='0,100' bgAngle='360' showBorder='0' startingAngle='70' >", caption);

            for (int i = 0; i < dt.Rows.Count; i++)
            {
                sb.AppendFormat(@"<set label='{0}' value='{1}'  />", dt.Rows[i][lableColumnInDataTableIndex].ToString(), dt.Rows[i][valueColumnInDataTableIndex].ToString());
            }
            sb.Append(@"</chart>");


            return FusionCharts.RenderChart(applicationPath + "/Charts/Pie3D.swf", "", sb.ToString(), caption, chartWidth.ToString(), chartHeight.ToString(), false, false);
        }
