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"); } }}

气泡图效果：

【vb.net】
