Create PowerPoint charts using C#

Learn how to create and customize charts in PowerPoint presentations programmatically using C# with the Syncfusion .NET PowerPoint library. This guide demonstrates adding various chart types and populating data to visualize information effectively.

Step 1: Create a new project

Start by creating a new C# Console Application project.

Step 2: Install the NuGet package

Add the Syncfusion.Presentation.Net.Core package to your project from NuGet.org.

Step 3: Add required namespaces to create PowerPoint charts

Add the following namespaces to your Program.cs file:

c#
using Syncfusion.OfficeChart;
using Syncfusion.Presentation;

Step 4: Create a PowerPoint presentation

Create a new presentation and add a blank slide.

Run

c#
//Create a new instance of PowerPoint Presentation file
IPresentation pptxDoc = Presentation.Create();
//Add a blank slide to the Presentation
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);

Step 5: Add a chart and populate data

Add a clustered column chart to the slide and populate it with sales data.

c#
//Add chart to the slide with position and size
IPresentationChart chart = slide.Charts.AddChart(100, 10, 700, 500);
//Specify the chart title
chart.ChartTitle = "Sales Analysis";
//Set chart data - Row1
chart.ChartData.SetValue(1, 2, "Jan");
chart.ChartData.SetValue(1, 3, "Feb");
chart.ChartData.SetValue(1, 4, "March");

//Set chart data - Row2
chart.ChartData.SetValue(2, 1, 2010);
chart.ChartData.SetValue(2, 2, 60);
chart.ChartData.SetValue(2, 3, 70);
chart.ChartData.SetValue(2, 4, 80);

//Set chart data - Row3
chart.ChartData.SetValue(3, 1, 2011);
chart.ChartData.SetValue(3, 2, 80);
chart.ChartData.SetValue(3, 3, 70);
chart.ChartData.SetValue(3, 4, 60);

//Set chart data - Row4
chart.ChartData.SetValue(4, 1, 2012);
chart.ChartData.SetValue(4, 2, 60);
chart.ChartData.SetValue(4, 3, 70);
chart.ChartData.SetValue(4, 4, 80);

//Create a new chart series with the name
IOfficeChartSerie seriesJan = chart.Series.Add("Jan");
//Set the data range of chart series – start row, start column, end row, end column
seriesJan.Values = chart.ChartData[2, 2, 4, 2];
//Create a new chart series with the name
IOfficeChartSerie seriesFeb = chart.Series.Add("Feb");
//Set the data range of chart series – start row, start column, end row, end column
seriesFeb.Values = chart.ChartData[2, 3, 4, 3];
//Create a new chart series with the name
IOfficeChartSerie seriesMarch = chart.Series.Add("March");
//Set the data range of chart series – start row, start column, end row, end column
seriesMarch.Values = chart.ChartData[2, 4, 4, 4];
//Set the data range of the category axis
chart.PrimaryCategoryAxis.CategoryLabels = chart.ChartData[2, 1, 4, 1];
//Specify the chart type
chart.ChartType = OfficeChartType.Column_Clustered;

Step 6: Save the PowerPoint presentation

Save the presentation with the chart to a file stream.

c#
//Save the PowerPoint presentation
FileStream outputStream = new(Path.GetFullPath(@"Output/Output.pptx"), FileMode.Create, FileAccess.ReadWrite);
pptxDoc.Save(outputStream);
//Close the output stream and presentation
outputStream.Close();
pptxDoc.Close();
