How to create Excel 3D line chart in C#, VB.NET?
This article explains how to create 3D line chart in Excel using Syncfusion Excel (XlsIO) library.
What is a 3D line chart?
3-D Line charts show each row or column of data as a 3-D Ribbon. 3-D Line charts can show trends over time (days, months, quarters or years), or categories. A 3-D Line chart has horizontal, vertical, and depth axes that you can change. The third axis can show some lines in front of others.
3D Line Chart
To create a 3D line chart in Excel using XlsIO, you need to do the following steps.
Steps to create 3D line chart
Step 1: Initialize chart
Create a chart object by calling the worksheet.Charts.Add method and specify the chart type to ExcelChartType.Line_3D enum value.
C#
//Create the chart
IChartShape chart = worksheet.Charts.Add();
//Set chart type to Line_3D
chart.ChartType = ExcelChartType.Line_3D;
Step 2: Assign data
Set a range of data from the worksheet to chart’s DataRange property. To plot the series values in column and categories in row, set chart’s IsSeriesInRows property to false.
C#
//Set region of Chart data
chart.DataRange = worksheet["A1:D6"];
//Set chart series in column for assigned data region
chart.IsSeriesInRows = false;
Step 3: Apply basic chart elements
Add the basic elements like chart title, data labels and legend.
- ChartTitle of chart object.
- Set DataLabels via DefaultDataPoints.
- Set TRUE to chart’s HasLegend property, to show the legend.
C#
//Apply chart elements
//Set Chart Title
chart.ChartTitle = "3D Line Chart";
//Set Datalabels
IChartSerie serie1 = chart.Series[0];
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
//Set Legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
Step 4: Apply 3D chart elements
Add the 3D chart elements like Rotation and Elevation.
- Rotation and Elevation of chart object.
C#
//Set Rotation and Elevation
chart.Rotation = 20;
chart.Elevation = 15;
chart.Perspective = 0;
Applicable properties for 3D line chart
Below is the list of other common properties applicable for 3D line chart.
- GapDepth
- PrimarySerieAxis (Depth Axis)Note:
Applying properties apart from the mentioned properties might throw exception or the changes will not be reflected in the output document because those properties are not related to line charts.

The following C#/ VB.NET complete code snippet shows the creation of 3D line chart using XlsIO.
C#
using Syncfusion.XlsIO;
using System.Reflection;
using System.IO;
namespace ChartSample
{
class Program
{
static void Main(string[] args)
{
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
application.DefaultVersion = ExcelVersion.Excel2016;
//Open existing workbook with data entered
Assembly assembly = typeof(Program).GetTypeInfo().Assembly;
Stream fileStream = assembly.GetManifestResourceStream("ChartSample.InputTemplate.xlsx");
IWorkbook workbook = application.Workbooks.Open(fileStream);
IWorksheet worksheet = workbook.Worksheets[0];
//Initialize chart
IChartShape chart = worksheet.Charts.Add();
chart.ChartType = ExcelChartType.Line_3D;
//Assign data
chart.DataRange = worksheet["A1:D6"];
chart.IsSeriesInRows = false;
//Apply chart elements
//Set Chart Title
chart.ChartTitle = "3D Line Chart";
//Set Legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
//Set datalabels
IChartSerie serie1 = chart.Series[0];
IChartSerie serie2 = chart.Series[1];
IChartSerie serie3 = chart.Series[2];
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie2.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie3.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
//Set Rotation and Elevation
chart.Rotation = 20;
chart.Elevation = 15;
chart.Perspective = 0;
//Positioning the chart in the worksheet
chart.TopRow = 8;
chart.LeftColumn = 1;
chart.BottomRow = 23;
chart.RightColumn = 8;
//Saving and closing the workbook
Stream stream = File.Create("Output.xlsx");
workbook.SaveAs(stream);
}
}
}
}
