Overview

A chart communicates data graphically on a slide. The Syncfusion .NET PowerPoint Library allows you to create, remove, and customize 80+ types of charts in PowerPoint presentations using C#, without Microsoft PowerPoint or interop dependencies.


How to create a chart in a PowerPoint presentation using C#

  1. Install NuGet package: Install the Syncfusion.Presentation.Net.Core NuGet package in your project.
  2. Create presentation: Create an instance of IPresentation to represent the presentation document.
  3. Add slide and chart: Add a blank slide as an ISlide and add a chart to the blank slide as an IPresentationChart.
  4. Set chart type: Set the chart type using the ChartType property.
  5. Set chart data range: Set the chart data range using the DataRange property and the data range values using the SetValue method.
  6. Save the presentation: Save the IPresentation object to the FileStream object.

Here is an example of how to create a pie chart in a PowerPoint presentation in C# using the Syncfusion .NET PowerPoint Library.

//Create an instance of presentation.
using IPresentation presentation = Presentation.Create();
//Add a blank slide to the presentation.
ISlide slide = presentation.Slides.Add(SlideLayoutType.Blank);
//Add a chart to the slide with position and size.
IPresentationChart chart = slide.Charts.AddChart(100, 10, 700, 500);
//Select the chart type.
chart.ChartType = OfficeChartType.Pie;

//Assign data range.
chart.DataRange = chart.ChartData[1, 1, 6, 2];
chart.IsSeriesInRows = false;

//Set the values for the chart data.
chart.ChartData.SetValue(1, 1, "Food");
chart.ChartData.SetValue(2, 1, "Fruits");
chart.ChartData.SetValue(3, 1, "Vegetables");
chart.ChartData.SetValue(4, 1, "Dairy");
chart.ChartData.SetValue(5, 1, "Protein");
chart.ChartData.SetValue(6, 1, "Grains");
chart.ChartData.SetValue(1, 2, "Percentage");
chart.ChartData.SetValue(2, 2, 36);
chart.ChartData.SetValue(3, 2, 14);
chart.ChartData.SetValue(4, 2, 13);
chart.ChartData.SetValue(5, 2, 28);
chart.ChartData.SetValue(6, 2, 9);

//Set data labels.
chart.Series[0].DataPoints.DefaultDataPoint.DataLabels.IsValue = true;

//Save the presentation.
using FileStream outputStream = new FileStream("Sample.pptx", FileMode.Create, FileAccess.ReadWrite);
presentation.Save(outputStream);
