How to create combination chart in Word document using C#?

4 mins read

Syncfusion Essential DocIO is a .NET Core Word library used to create, read, and edit Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can create combination chart in Word document in C#.

What is a combination cone chart?

Combination charts combine two or more chart types to make the data easy to understand. These charts can be used when the numbers in your data vary widely from data series to data series, or you have mixed type of data.

Combination chart in Word document

Steps to create combination chart in Word document:

Initialize chart.

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

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

Select SerieType to create a combination chart.

Set different SerieType value to the series. By doing this, chart type will be changed to combination chart type.

//Set Serie type.
series1.SerieType = OfficeChartType.Column_Clustered;
series2.SerieType = OfficeChartType.Line;
series2.UsePrimaryAxis = false;

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 = "Combination Chart";
 
//Set Datalabels.
series1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
 
//Set legend.
chart.HasLegend = true;
chart.Legend.Position = OfficeLegendPosition.Bottom;

The following C# code sample shows the creation of combination 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, "Month");
    chart.ChartData.SetValue(2, 1, "Jan");
    chart.ChartData.SetValue(3, 1, "Feb");
    chart.ChartData.SetValue(4, 1, "Mar");

    chart.ChartData.SetValue(12, 3, 6620);
    chart.ChartData.SetValue(13, 3, 5085);
    //Set region of Chart data.
    chart.DataRange = chart.ChartData[1, 1, 13, 3];
    //Set chart series in the column for assigned data region.
    chart.IsSeriesInRows = false;
    //Set a Chart Title.
    chart.ChartTitle = "Combination Chart";
    //Set Datalabels.
    IOfficeChartSerie series1 = chart.Series[0];
    IOfficeChartSerie series2 = chart.Series[1];
    //Set Serie type.
    series1.SerieType = OfficeChartType.Column_Clustered;
    series2.SerieType = OfficeChartType.Line;

    series1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
    //Set legend.
    chart.HasLegend = true;
    chart.Legend.Position = OfficeLegendPosition.Bottom;
    //Set chart type.
    chart.ChartType = OfficeChartType.Combination_Chart;
    //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)
    }
}
