When we work with the pie chart on the presentation slide, we may need to separate each part of pie chart to make them stand out. This article is going to introduce the method of how to set the pie explosion for the pie chart on the presentation slides in C# by using Spire.Presentation.

Spire.Presentation offers a property of chart.Series[].Distance to enable developers to pull the whole pie apart by exploding the pie chart.

On Microsoft PowerPoint, We can adjust the percentage of "Pie Explosion" on the Series Options at the "Format Data Series" area to control the distance between each section in the chart.

Step 1: Create a presentation document and load the file from disk.

Presentation ppt = new Presentation();
ppt.LoadFromFile("Sample.pptx");

Step 2: Get the chart that needs to set the point explosion.

IChart chart = ppt.Slides[0].Shapes[0] as IChart;

Step 3: Explode the pie chart.

chart.Series[0].Distance = 15;

Step 4: Save the document to file.

ppt.SaveToFile("Result.pptx", FileFormat.Pptx2010);

Full codes:

using Spire.Presentation;
using Spire.Presentation.Charts;

namespace ExplodePie
{
    class Program
    {
        static void Main(string[] args)
        {
            Presentation ppt = new Presentation();
            ppt.LoadFromFile("Sample.pptx");

            IChart chart = ppt.Slides[0].Shapes[0] as IChart;

            chart.Series[0].Distance = 15;

            ppt.SaveToFile("Result.pptx", FileFormat.Pptx2010);
        }
    }
