How to create Excel stacked line chart in C#, VB.NET?
This article explains how to create a stacked line chart in Excel using the Syncfusion® Excel (XlsIO) library.
What is a stacked line chart?
A stacked line chart displays series as a line. The values are represented on the y-axis and the categories are displayed on the x-axis.
Stacked line chart created using XlsIO
To create a stacked line chart in Excel using XlsIO, you need to follow the steps below.
Steps to create a stacked line chart
Step 1: Initialize the chart
Create a chart object by calling the worksheet.Charts.Add method and specify the chart type as ExcelChartType.Line_Stacked enum value.
C#
// Create the chart IChartShape chart = worksheet.Charts.Add(); // Set chart type to Line_Stacked chart.ChartType = ExcelChartType.Line_Stacked;
Step 2: Assign data
Set a range of data from the worksheet to the chart’s `DataRange` property. To plot the series values in columns and categories in rows, set the chart’s `IsSeriesInRows` property to false.
C#
// Set region of chart data chart.DataRange = worksheet["A1:D6"]; // Set chart series in columns for the assigned data region chart.IsSeriesInRows = false;
Step 3: Apply basic chart elements
Add the basic elements like the chart title, legend and datalabels.
- ChartTitle of the chart object.
- Set DataLabels via DefaultDataPoint.
- Set TRUE to the chart’s HasLegend property, to show the legend.
C#
// Apply chart elements // Set Chart Title chart.ChartTitle = "Stacked Line Chart"; // Set DataLabels IChartSerie serie1 = chart.Series[0]; serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true; serie1.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center; // Set Legend chart.HasLegend = true; chart.Legend.Position = ExcelLegendPosition.Bottom;
Applicable properties for a stacked line chart
Common property applicable for a stacked line chart is,
- IsVarycolor (This property holds good for single series chart).Note:
Applying properties apart from the mentioned property might throw an exception, or the changes will not be reflected in the output document because those properties are not related to a line chart.
To know more about creating charts with various settings using XlsIO, please refer to the documentation.
The following C#/VB.NET complete code snippet shows the creation of a stacked 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_Stacked;
// Assign data
chart.DataRange = worksheet["A1:D6"];
chart.IsSeriesInRows = false;
// Apply chart elements
// Set chart Title
chart.ChartTitle = "Stacked 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;
serie1.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
serie2.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
serie3.DataPoints.DefaultDataPoint.DataLabels.Position = ExcelDataLabelPosition.Center;
// 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);
}
}
}
}
