Stacked Pyramid chart in Word document

Steps to create stacked pyramid chart in Word document:

Step 1: Initialize chart

Create a chart object by calling the paragraph.AppendChart(446,270) method and specify the chart type to the OfficeChartType.Pyramid_Stacked enum value.

//Create and append the chart to the paragraph.
WChart chart = paragraph.AppendChart(446, 270);
//Set chart type.
chart.ChartType = OfficeChartType.Pyramid_Stacked;

Step 2: Assign data and chart elements

Add the basic elements like the chart title, data labels and legend.

Assign data.
ChartTitle of the chart object.
Set DataLabels using the DefaultDataPoint.
Set TRUE to the chart’s HasLegend property to show the legend, else False.

//Set region of Chart data.
chart.DataRange = chart.ChartData[1, 1, 6, 4];
 
//Apply the chart elements.
//Set a chart title.
chart.ChartTitle = "Stacked Pyramid Chart";
 
//Set Datalabels.
IOfficeChartSerie series1 = chart.Series[0];
series1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
 
//Set legend.
chart.HasLegend = true;
chart.Legend.Position = OfficeLegendPosition.Bottom;

Step 3: Apply 3D chart elements

Add the 3D charts elements like Rotation and Elevation.

Rotation of the chart object.
Elevation of the chart object.

//Set rotation and elevation.
Chart.Rotation = 50;
chart.Elevation = 20;

Below is a list of other common properties applicable for stacked bar pyramid chart.

GapWidth
GapDepth
BarShapeBase and BarShapeTop (to change the shape of the column / bar)
Note:

The following C# code sample shows the creation of stacked pyramid chart using the Word library.

//Create a new Word document.
using (WordDocument document = new WordDocument())
{
    //Add a section to the document.
    IWSection section = document.AddSection();
    //Add a paragraph to the section.
    IWParagraph paragraph = section.AddParagraph();
    //Create and append the chart to the paragraph.
    WChart chart = paragraph.AppendChart(446, 270);
    //Set chart data.
    chart.ChartData.SetValue(1, 1, "Fruits");
    chart.ChartData.SetValue(2, 1, "Apples");
    chart.ChartData.SetValue(3, 1, "Grapes");
    chart.ChartData.SetValue(4, 1, "Bananas");
    chart.ChartData.SetValue(5, 1, "Oranges");
    chart.ChartData.SetValue(6, 1, "Melons");
    chart.ChartData.SetValue(1, 2, "Joey");
    chart.ChartData.SetValue(2, 2, 5);
    chart.ChartData.SetValue(3, 2, 4);
    chart.ChartData.SetValue(4, 2, 4);
    chart.ChartData.SetValue(5, 2, 2);
    chart.ChartData.SetValue(6, 2, 2);
    chart.ChartData.SetValue(1, 3, "Matthew");
    chart.ChartData.SetValue(2, 3, 3);
    chart.ChartData.SetValue(3, 3, 5);
    chart.ChartData.SetValue(4, 3, 4);
    chart.ChartData.SetValue(5, 3, 1);
    chart.ChartData.SetValue(6, 3, 7);
    chart.ChartData.SetValue(1, 4, "Peter");
    chart.ChartData.SetValue(2, 4, 2);
    chart.ChartData.SetValue(3, 4, 2);
    chart.ChartData.SetValue(4, 4, 3);
    chart.ChartData.SetValue(5, 4, 5);
    chart.ChartData.SetValue(6, 4, 6);
    //Set region of Chart data.
    chart.DataRange = chart.ChartData[1, 1, 6, 4];
    //Set chart series in the column for assigned data region.
    chart.IsSeriesInRows = false;
    //Set a Chart Title.
    chart.ChartTitle = "Stacked Pyramid Chart";
    //Set Datalabels.
    IOfficeChartSerie series1 = chart.Series[0];
    IOfficeChartSerie series2 = chart.Series[1];
    IOfficeChartSerie series3 = chart.Series[2];
 
    series1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
    series2.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
    series3.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
    //Set legend.
    chart.HasLegend = true;
    chart.Legend.Position = OfficeLegendPosition.Bottom;
    //Set chart type.
    chart.ChartType = OfficeChartType.Pyramid_Stacked;
    //Set rotation and elevation.
    chart.Rotation = 50;
    chart.Elevation = 20;
    //Create a file stream.
    using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"../../../Sample.docx"), FileMode.Create, FileAccess.ReadWrite))
    {
        //Save the Word document to the file stream.
        document.Save(outputFileStream, FormatType.Docx);
    }
}
