How to create WinForms Excel scatter with straight lines chart?
Our WinForms XIsIO’s feature tour page explains how to create a scatter with straight line chart in Excel using the Syncfusion® Excel (XlsIO) library.
What is a scatter with straight line chart?
A scatter with straight line chart is used to compare at least two sets of values or pairs of data. The values are represented with a connected straight line.
Scatter with Straight Line Chart
To create a scatter with straight line chart in Excel using XlsIO, you need to to follow the steps below.
Steps to create scatter with straight line chart:
Step 1: Initialize chart
Create a chart object by calling the worksheet.Charts.Add method and specify the chart type to the ExcelChartType.Scatter_Line enum value.
C#
// Create the chart IChartShape chart = worksheet.Charts.Add(); // Set chart type to Scatter_Line chart.ChartType = ExcelChartType.Scatter_Line;
Step 2: Assign data
Set a range of data from the worksheet to the chart’s DataRange property. To plot the series values in a column and categories in a row, set the chart’s IsSeriesInRows property to false.
C#
// Set region of chart data chart.DataRange = worksheet["A3:B7"]; // 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 DefaultDataPoint.
- Set TRUE to chart’s HasLegend property to show the legend. Else FALSE.
C#
// Apply chart elements // Set Chart Title chart.ChartTitle = "Scatter With Straight Line Chart"; // Set Legend chart.HasLegend = false; // Set DataLabels IChartSerie serie = chart.Series[0]; serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = true; serie.DataPoints.DefaultDataPoint.DataLabels.IsCategoryName = true;
Applicable properties for scatter with straight lines chart
Property applicable for a scatter with straight line chart along with the common line properties is:
- IsVaryColor Note:
Applying properties apart from the mentioned property and line properties might throw an exception or the changes will not be reflected in the output document because those properties are not related to scatter charts.

The following C#/ VB.NET complete code snippet shows the creation of scatter with straight 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.Scatter_Line; // Assign data chart.DataRange = worksheet["A3:B7"]; chart.IsSeriesInRows = false; // Apply chart elements //Set Chart Title chart.ChartTitle = "Scatter With Straight Line Chart"; // Set Legend chart.HasLegend = false; // Set DataLabels IChartSerie serie = chart.Series[0]; serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true; serie1.DataPoints.DefaultDataPoint.DataLabels.IsCategoryName = true; //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); } } } }
VB.NET
Imports Syncfusion.XlsIO Imports System.Reflection Imports System.IO Namespace ChartSample Class Program Public Shared Sub Main(ByVal args As String()) Using excelEngine As ExcelEngine = New ExcelEngine() Dim application As IApplication = excelEngine.Excel application.DefaultVersion = ExcelVersion.Excel2016 'Open existing workbook with data entered Dim assembly As Assembly = GetType(Program).GetTypeInfo().Assembly Dim fileStream As Stream = assembly.GetManifestResourceStream("ChartSample.InputTemplate.xlsx") Dim workbook As IWorkbook = application.Workbooks.Open(fileStream) Dim worksheet As IWorksheet = workbook.Worksheets(0) 'Initialize chart Dim chart As IChartShape = worksheet.Charts.Add() chart.ChartType = ExcelChartType.Scatter_Line 'Assign data chart.DataRange = worksheet("A3:B7") chart.IsSeriesInRows = False 'Apply chart elements 'Set Chart Title chart.ChartTitle = "Scatter With Straight Line Chart" 'Set Legend chart.HasLegend = False 'Set DataLabels IChartSerie serie = chart.Series[0] serie.DataPoints.DefaultDataPoint.DataLabels.IsValue = True serie.DataPoints.DefaultDataPoint.DataLabels.IsCategoryName = True 'Positioning chart in the worksheet chart.TopRow = 8 chart.LeftColumn = 1 chart.BottomRow = 23 chart.RightColumn = 8 'Saving and closing the workbook Dim stream As Stream = File.Create("Output.xlsx") workbook.SaveAs(stream) End Using End Sub End Class End Namespace
