C# 在Excel中气泡图

气泡图（Bubble Chart）是可用于展示三个变量之间的关系。通过绘制x 值， y 值和大小值即可确定图表中气泡的坐标及大小。下面通过后端C\#代码及VB.NET代码展示如何来实现在Excel中创建气泡图的方法。

**程序环境：**

*  Visual Studio
 *  .Net FrameWork 4.5.1
 *  Spire.XLS for .NET Version 10.12.0

注：编辑代码前先将Spire.Xls.dll（dll文件可在解压包Bin文件夹下获取）添加引用至VS程序，可通过*[官网下载][Link 1]*或者*[Nuget][]*下载。参考如下引用效果：

【C\#】

using Spire.Xls;
    using Spire.Xls.Charts;
    using System.Drawing;
    
    namespace CreateBubbleChart_XLS
    {
        class Program
        {
            static void Main(string[] args)
            {
                //创建一个Excel工作簿，并获取第一张工作表
                Workbook wb = new Workbook();
                wb.Version = ExcelVersion.Version2013;
                Worksheet sheet = wb.Worksheets[0];          
    
                //添加图表，指定图表类型
                Chart chart = sheet.Charts.Add();
                chart.ChartType = ExcelChartType.Bubble;
                chart.PrimaryCategoryAxis.Title = "人均消费";
                chart.PrimaryValueAxis.Title = "点评数";
    
                //设置图表的名称和数据
                Spire.Xls.Charts.ChartSerie cs1 = chart.Series.Add("气泡图");
                cs1.EnteredDirectlyValues = new object[]{2, 5, 3, 6, 7};
                cs1.EnteredDirectlyCategoryLabels = new object[]{1, 4.5, 1.2, 3.3, 2};
                cs1.EnteredDirectlyBubbles = new object[]{3, 6, 1, 4, 7};           
    
                //设置图表位置
                chart.LeftColumn = 4;
                chart.TopRow = 2;
                chart.RightColumn = 12;
                chart.BottomRow = 22;
    
                //设置图表标题
                chart.ChartTitle = "人均消费VS点评数";
                chart.ChartTitleArea.IsBold = true;
                chart.ChartTitleArea.Size = 12;    
                chart.Legend.Position = LegendPositionType.Top;
    
                //保存文档
                wb.SaveToFile("BubbleChart.xlsx", ExcelVersion.Version2013);
                System.Diagnostics.Process.Start("BubbleChart.xlsx");
            }
        }
    }
