使用FusionCharts出柱状图和饼状图

时间：2021-03-26 08:57:46

在最近的项目中，需要使用出图，能够查看柱状图，饼状图等效果，刚开始我们用JS写的效果，发现效果不理想，找了一个JS插件发现效果还是不理想，客户也不满意，客户希望要很炫的效果，最后我们使用了FusionCharts。

FusionCharts是一个Flash的图表组件，它可以用来制作数据动画图表，其中动画效果用的是Adobe Flash 8 （原Macromedia Flash的）制作的flash ， FusionCharts可用于任何网页的脚本语言类似于HTML ， .NET，ASP ， JSP技术的， PHP ， ColdFusion等，提供互动性和强大的图表。使用XML作为其数据接口， FusionCharts充分利用流体美丽的Flash创建紧凑，互动性和视觉逮捕图表。当然他的有点我就不说了，百科上说的很多...

为了很炫，我们就使用的是FusionCharts里面的MSColumn3D.swf和Pie3D.swf的3D效果，具体不说了，直接贴代码了，这样看着清楚。

（1）创建柱状图的关键代码

   public void CreateChart(List<AJSLTJModel> list)

        {

            string strCategories;

            string strCategories2;

            strchartXML = "<graph  formatNumber='0'  formatNumberScale='0' >";

            strchartXML2 = "<graph  formatNumber='0'  formatNumberScale='0' >";

            strCategories = "<categories>";

            strCategories2 = "<categories>";

            string strDataCurr1 = "<dataset seriesName='登记数量' color='AFD8F8'>";

            string strDataPrev1 = "<dataset seriesName='登记面积' color='F6BD0F'>";

            for (int i = 0; i < list.Count; i++)

            {

                AJSLTJModel ajstjModel = list[i];

                string catagry = ajstjModel.ResYear + "年" + ajstjModel.ResMonth + "月";

                string resTJSL = ajstjModel.ResDJSL.ToString();

                string resTJMJ = ajstjModel.ResDJMJ.ToString();

                strCategories += "<category name='" + catagry + "' />";

                strCategories2 += "<category name='" + catagry + "' />";

                strDataCurr1 += "<set value='" + resTJSL + "' />";

                strDataPrev1 += "<set value='" + resTJMJ + "' />";

            }

            strCategories += "</categories>";

            strCategories2 += "</categories>";

            strDataCurr1 += "</dataset>";

            strDataPrev1 += "</dataset>";

            strchartXML += strCategories + strDataCurr1 + "</graph>";

            strchartXML2 += strCategories2 + strDataPrev1 + "</graph>";

            ClientScript.RegisterStartupScript(this.GetType(), "showDiv", " <script> updateChart(\"" + strchartXML + "\",\"" + strchartXML2 + "\") </script> ");

        }

（2）创建饼状图的关键代码

  public void CreateChartPie(List<AJSLTJModel> list)

        {

            strchartXMLPie1 = "<chart palette='4' decimals='0' enableSmartLabels='1' enableRotation='0' bgColor='99CCFF,FFFFFF' bgAlpha='40,100' bgRatio='0,100' bgAngle='360' showBorder='1' startingAngle='70' >";

            strchartXMLPie2 = "<chart palette='4' decimals='0' enableSmartLabels='1' enableRotation='0' bgColor='99CCFF,FFFFFF' bgAlpha='40,100' bgRatio='0,100' bgAngle='360' showBorder='1' startingAngle='70' >";

            string strDataCurr1 = "";

            string strDataCurr2 = "";

            for (int i = 0; i < list.Count; i++)

            {

                AJSLTJModel ajstjModel = list[i];

                string catagry = ajstjModel.ResYear + "年" + ajstjModel.ResMonth + "月";

                string resTJSL = ajstjModel.ResDJSL.ToString();

                string resTJMJ = ajstjModel.ResDJMJ.ToString();

                strDataCurr1 += "<set label='"+catagry+"' value='"+resTJSL+"' />";

                strDataCurr2 += "<set label='" + catagry + "' value='" + resTJMJ + "' />";

            }

            strchartXMLPie1 += strDataCurr1 + "</chart>";

            strchartXMLPie2 += strDataCurr2 + "</chart>";

            ClientScript.RegisterStartupScript(this.GetType(), "showDiv", " <script> updatePie(\"" + strchartXMLPie1 + "\",\"" + strchartXMLPie2 + "\") </script> ");

        }

（3)前台JS代码：

  function updateChart(strchartXML,strchartXML2) {

            var chart1div = document.getElementById("chart1div");

            if (chart1div != null) {

                var chart1 = new FusionCharts("../FusionChart/MSColumn3D.swf", "chart1Id", screen.width - 400, screen.height - 500, "0", "0");

                chart1.addParam("wmode", "Opaque");

                chart1.setDataXML(strchartXML);

                chart1.render("chart1div");

            }

            var chart2div = document.getElementById("chart2div");

            if (chart2div != null) {

                var chart2 = new FusionCharts("../FusionChart/MSColumn3D.swf", "chart2Id", screen.width - 400, screen.height - 500, "0", "0");

                chart2.addParam("wmode", "Opaque");

                chart2.setDataXML(strchartXML2);

                chart2.render("chart2div");

            }

        }

        function updatePie(strchartXMLPie1, strchartXMLPie2) {

            var pie1div = document.getElementById("pie1div");

            if (pie1div != null) {

                var pie1 = new FusionCharts("../FusionChart/Pie3D.swf", "pie1Id", screen.width - 400, screen.height - 500, "0", "0");

                pie1.addParam("wmode", "Opaque");

                pie1.setDataXML(strchartXMLPie1);

                pie1.render("pie1div");

            }

            var pie2div = document.getElementById("pie2div");

            if (pie2div != null) {

                var pie2 = new FusionCharts("../FusionChart/Pie3D.swf", "pie2Id", screen.width - 400, screen.height - 500, "0", "0");

                pie2.addParam("wmode", "Opaque");

                pie2.setDataXML(strchartXMLPie2);

                pie2.render("pie2div");

            }

        }

（4）还是看看效果图吧

使用FusionCharts出柱状图和饼状图

OK，很炫吧，打开的时候如同雨后春笋，3D效果就是炫....使用完毕
