Create a Column Chart in Word in C

Spire.Doc for .NET offers the Section.AddParagraph.AppendChart(ChartType chartType,float width, float height) method to add a specific type of chart to a paragraph. The following is the sample code to create a simple column chart in Word.

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields.Shapes.Charts;
using Spire.Doc.Fields;

namespace WordChart
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create a Document instance
            Document document = new Document();

            //Create a new section
            Section section = document.AddSection();

            //Create a new paragraph and append text
            section.AddParagraph().AppendText("Create a Column chart in Word");

            //Add a new paragraph to append a column chart
            Paragraph newPara = section.AddParagraph();
            ShapeObject shape = newPara.AppendChart(ChartType.Column, 500, 300);

            //Clear the chart's series data to start with a clean chart
            Chart chart = shape.Chart;
            chart.Series.Clear();

            //Add chart data
            chart.Series.Add("Total Sales",
                new[] { "Team1", "Team2", "Team3", "Team4", "Team5" },
                new double[] { 1900000, 850000, 2100000, 600000, 1500000 });

            //Set the number format 
            chart.AxisY.NumberFormat.FormatCode = "#,##0";

            //Save the result file
            document.SaveToFile("AppendColumnChart.docx", FileFormat.Docx);
        }
    }
}

Create a Line Chart in Word in C

To create a line chart you just need to set the ChartType parameter to Line and then add some chart data. In addition, Spire.Doc for .NET also allows the creation of pie chart, bar chart, bubble chart, surface3D chart, etc. The following is the complete sample code to create a line chart.

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields.Shapes.Charts;
using Spire.Doc.Fields;

namespace WordChart
{
    class Program
    {
        static void Main(string[] args)
        {
            //Create a Document instance
            Document document = new Document();

            //Create a new section
            Section section = document.AddSection();

            //Add a new paragraph and append text
            section.AddParagraph().AppendText("Create a Line Chart in Word");

            //Add a new paragraph to append line chart
            Paragraph newPara = section.AddParagraph();
            ShapeObject shape = newPara.AppendChart(ChartType.Line, 500, 300);

            //Set chart title  
            Chart chart = shape.Chart;
            ChartTitle title = chart.Title;
            title.Text = "My Chart";

            ChartSeriesCollection seriesColl = chart.Series;
            seriesColl.Clear();

            //Set chart data
            string[] categories = { "C1", "C2", "C3", "C4", "C5", "C6" };
            seriesColl.Add("AW Series 1", categories, new double[] { 1, 2, 2.5, 4, 5, 6 });
            seriesColl.Add("AW Series 2", categories, new double[] { 2, 3, 3.5, 6, 6.5, 7 });

            //Save the result document
            document.SaveToFile("AppendLineChart.docx", FileFormat.Docx);
        }
    }
}
