Pie Chart

Pie charts, the most common tools used for data visualization, are circular graphs that display the proportionate contribution of each category, which is represented by a pie or a slice. The magnitude of the dependent variable is proportional to the angle of the slice. These charts can be used for plotting just one series with non-zero and positive values.

DsExcel supports the following types of pie charts.

Chart Type	Chart Snapshot	Use Case
Pie		Pie chart is used to display a single data series in a circle-type structure, with each sector representing a different category.
Pie3D		Pie3D chart is used to display the chart demonstration in 3D which is a modification of 2DPie chart in terms of appearance.
PieExploded		PieExploded chart is used to pull all of the slices out of a pie chart and view the sectors separately in pieces.
PieExploded3D		PieExploded 3D chart is used display the chart demonstration in 3D which is a modification of 2DPieExploded chart.
PieOfPie		PieofPie chart is used to separate the slices from the main pie chart and display them in an additional pie chart.
BarOfPie		BarofPie chart is used to separate the slices from the main pie chart and display them in an additional stacked bar chart.
Doughnut		Doughnut chart is used to display multiple data series concurrently, with each ring depicting a single data series.
DoughnutExploded		DoughnutExploded is used to pull all slices out of a DoughnutExploded chart and view the sectors separately in pieces.

Using Code

Refer to the following code to add Doughnut Exploded chart:

public void PieCharts()
{
      // Initialize workbook
      Workbook workbook = new Workbook();
      // Fetch default worksheet 
      IWorksheet worksheet = workbook.Worksheets[0];

      // Prepare data for chart
      worksheet.Range["A1:D4"].Value = new object[,]
      {
           {null, "Q1", "Q2", "Q3"},
           {"Mobile Phones", 1330, 2345, 3493},
           {"Laptops", 2032, 3632, 2197},
           {"Tablets", 6233, 3270, 2030}
      };
      worksheet.Range["A:D"].Columns.AutoFit();
      // Add Pie Chart
      IShape pieChartshape = worksheet.Shapes.AddChart(ChartType.DoughnutExploded, 250, 20, 360, 230);

      // Adding series to SeriesCollection
      pieChartshape.Chart.SeriesCollection.Add(worksheet.Range["A1:D4"], RowCol.Columns, true, true);

      // Configure Chart Title 
      pieChartshape.Chart.ChartTitle.TextFrame.TextRange.Paragraphs.Add("Annual Sales Record");

      // Saving workbook to Xlsx
      workbook.Save(@"22-PieChart.xlsx", SaveFileFormat.Xlsx);
  }
