In Excel, we could use charts to visualize and compare data. However, once the charts are created, it becomes much difficult for us to read the data precisely from charts. Adding a data table below the chart is a good solution for which the chart and data are on the same place. This article is going to introduce the method to add a data table to the chart that is based on the data in C# using Spire.XLS.
Note: before start, please download the latest version of Spire.XLS and add the .dll in the bin folder as the reference of Visual studio.
Step 1: Create a new workbook and add an empty sheet.
Workbook workbook = new Workbook();
workbook.CreateEmptySheets(1);
Worksheet sheet = workbook.Worksheets[0];
Step 2: Fill cells with sample data.
sheet.Name = "Demo";
sheet.Range["A1"].Value = "Month";
sheet.Range["A2"].Value = "Jan.";
sheet.Range["A3"].Value = "Feb.";
sheet.Range["A4"].Value = "Mar.";
sheet.Range["A5"].Value = "Apr.";
sheet.Range["A6"].Value = "May.";
sheet.Range["A7"].Value = "Jun.";
sheet.Range["B1"].Value = "Peter";
sheet.Range["B2"].NumberValue = 3.3;
sheet.Range["B3"].NumberValue = 2.5;
sheet.Range["B4"].NumberValue = 2.0;
sheet.Range["B5"].NumberValue = 3.7;
sheet.Range["B6"].NumberValue = 4.5;
sheet.Range["B7"].NumberValue = 4.0;
sheet.Range["C1"].Value = "George";
sheet.Range["C2"].NumberValue = 3.8;
sheet.Range["C3"].NumberValue = 3.2;
sheet.Range["C4"].NumberValue = 1.7;
sheet.Range["C5"].NumberValue = 3.5;
sheet.Range["C6"].NumberValue = 4.5;
sheet.Range["C7"].NumberValue = 4.3;
sheet.Range["D1"].Value = "Macbeth";
sheet.Range["D2"].NumberValue = 3.0;
sheet.Range["D3"].NumberValue = 2.8;
sheet.Range["D4"].NumberValue = 3.5;
sheet.Range["D5"].NumberValue = 2.3;
sheet.Range["D6"].NumberValue = 3.3;
sheet.Range["D7"].NumberValue = 3.8;
Step 3: Create a Column3DClustered based on the sample data.
Chart chart = sheet.Charts.Add(ExcelChartType.Column3DClustered);
chart.DataRange = sheet.Range["B1:D7"];
chart.SeriesDataFromRange = false;
chart.TopRow = 7;
chart.BottomRow = 28;
chart.LeftColumn = 3;
chart.RightColumn =11;
chart.ChartTitle = "Chart with Data Table";
chart.ChartTitleArea.IsBold = true;
chart.ChartTitleArea.Size = 12;
Spire.Xls.Charts.ChartSerie cs1 = chart.Series[0];
cs1.CategoryLabels = sheet.Range["A2:A7"];
Step 4: Add a data table to the chart that is based on the data.
chart.HasDataTable = true;
Step 5: Save the document and launch to see effects.
workbook.SaveToFile("S3.xlsx", ExcelVersion.Version2010);
System.Diagnostics.Process.Start("S3.xlsx");
