How to create a doughnut chart in Presentation document in WinForms?
The PowerPoint framework is a feature rich .NET PowerPoint
library that can be
used by developers to create, read, edit and convert PowerPoint files to PDFs
and images programmatically without Office or interop dependencies. Using this
library, you can create a doughnut
chart in Presentation document
Steps to create a doughnut chart in Presentation document using C# and VB.NET:
- Create a new C# console application project.
2. Install the Syncfusion.Presentation.WinForms NuGet package as a reference to your .NET Framework applications from NuGet.org
- Include the following namespace in the Program.cs file.
C#
using Syncfusion.Presentation; using Syncfusion.OfficeChart;
VB
Imports Syncfusion.Presentation Imports Syncfusion.OfficeChart
- Use the following code example to create a doughnut chart in Presentation document.
C#
// Create a Presentation instance.
using (IPresentation pptxDoc = Presentation.Create())
{
//Add a blank slide to the Presentation.
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.Blank);
//Add chart to the slide with position and size.
IPresentationChart chart = slide.Charts.AddChart(100, 10, 500, 500);
//Set the chart type.
chart.ChartType = OfficeChartType.Doughnut;
//Set the chart line pattern.
chart.ChartArea.Border.LinePattern = OfficeChartLinePattern.None;
//Set the Chart title.
chart.ChartTitle = "Current 963 Schematic Health";
chart.ChartTitleArea.FontName = "Helvetica";
chart.ChartTitleArea.Size = 10;
//Set the Chart data.
chart.ChartData.SetValue(2, 1, "Good");
chart.ChartData.SetValue(2, 2, 2);
chart.ChartData.SetValue(3, 1, "Config errors [Missing graphic]");
chart.ChartData.SetValue(3, 2, 4);
chart.ChartData.SetValue(4, 1, "Config errors [Broken GOTO link]");
chart.ChartData.SetValue(4, 2, 8);
chart.ChartData.SetValue(5, 1, "Config errors [Orphan points]");
chart.ChartData.SetValue(5, 2, 14);
//Create a series for the chart.
IOfficeChartSerie pieSeries = chart.Series.Add("");
pieSeries.Values = chart.ChartData[2, 2, 5, 2];
//Set the Chart labels.
pieSeries.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
pieSeries.DataPoints.DefaultDataPoint.DataLabels.Color = OfficeKnownColors.White;
//Set the chart legend.
chart.Legend.TextArea.FontName = "Helvetica";
chart.Legend.TextArea.Size = 10;
chart.PrimaryCategoryAxis.CategoryLabels = chart.ChartData[2, 1, 5, 1];
chart.Legend.Position = OfficeLegendPosition.Right;
chart.Legend.IncludeInLayout = true;
chart.Legend.FrameFormat.Border.AutoFormat = true;
chart.Legend.FrameFormat.Border.IsAutoLineColor = true;
//Set the chart legend positions.
chart.Legend.Layout.ManualLayout.Left = 0.668;
chart.Legend.Layout.ManualLayout.Top = 0.355;
chart.Legend.Layout.ManualLayout.Height = 0.413;
chart.Legend.Layout.ManualLayout.Width = 0.319;
chart.Legend.Layout.ManualLayout.LeftMode = LayoutModes.edge;
chart.Legend.Layout.ManualLayout.TopMode = LayoutModes.edge;
//Set the chart plot area positions.
chart.PlotArea.Layout.ManualLayout.Left = 0.122;
chart.PlotArea.Layout.ManualLayout.Top = 0.239;
chart.PlotArea.Layout.ManualLayout.Height = 0.433;
chart.PlotArea.Layout.ManualLayout.Width = 0.417;
chart.PlotArea.Layout.ManualLayout.LeftMode = LayoutModes.edge;
chart.PlotArea.Layout.ManualLayout.TopMode = LayoutModes.edge;
chart.PlotArea.Layout.LayoutTarget = LayoutTargets.inner;
//Save the Presentation.
pptxDoc.Save("DoughnutChart.pptx");
}
