How to create Excel 3D line chart in C#, VB.NET?

7 mins read

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.

            //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.

            //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.

              //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.

              //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.

                chart.TopRow = 8;
                chart.LeftColumn = 1;
                chart.BottomRow = 23;
