Create Various Types of Charts in Word Documents in C# and VB.NET

Charts can help communicate complex data at a glance and make it easier for readers to understand trends, patterns, and relationships within the data. You may need to create charts in a Word document when you want to visually represent data or information for better understanding. For example, if you're creating a report on sales data, adding a chart showing the revenue generated over a period of time can quickly give your audience a clear view of the company's performance. Similarly, if you're presenting survey results, a pie chart or bar graph can help visualize the percentage distribution of responses. Charts can also be useful for comparing data across different categories or variables, such as comparing the performance of different departments or products. By creating charts in your Word document, you can enhance the impact of your content and make it more engaging and informative for your readers. In this article, we will explore how to create various types of charts in a Word document using C# and VB.NET.

Installation

To create charts in Word documents, you will need to use an appropriate library. One of the popular libraries for this task is Microsoft Word Interop, but it has limitations such as requiring Microsoft Word to be installed and not being recommended for server-side usage. To circumvent this issue, we'll be utilizing the Free Spire.Doc for .NET library which allows for manipulating Word documents without relying on Microsoft Office. You can follow these steps to install the library via NuGet:

Open the Package Manager Console.
Execute this command: Install-Package FreeSpire.Doc

Create Various Types of Charts in Word Documents in C# and VB.NET

Once you have completed the installation, you can start creating charts in your Word documents. The following are the basic steps involved in creating a chart:

Initialize an instance of the Document class.
Add a section using Document.AddSection() method.
Add a paragraph to the section using Section.AddParagraph() method.
Add a chart shape to the paragraph using Paragraph.AppendChart() method.
Access the chart object using ShapeObject.Chart property.
Add data series to the chart using Chart.Series.Add() method.
Save the result document using Document.SaveToFile() method.

Now you know the basic steps for creating charts in a Word document, let's take a look at how you can create different types of charts, for example, column charts, line charts, pie charts, scatter charts, bar charts, bubble charts, and 3D surface charts.

Create a Column Chart in Word in C# and VB.NET

A column chart is a great way to compare data across categories. To create a column chart in Word using C# or VB.NET, you can use the following code:

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

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

            //Create a new section
            Section section = document.AddSection();
            section.PageSetup.Margins.All = 72f;

            //Create a new paragraph and append text
            Paragraph paragraph = section.AddParagraph();
            paragraph.AppendText("Column Chart");
            paragraph.ApplyStyle(BuiltinStyle.Heading1);

            //Create a new paragraph to append a column chart shape
            paragraph = section.AddParagraph();
            ShapeObject shape = paragraph.AppendChart(ChartType.Column, 300, 200);

            //Clear the default series of the chart
            Chart chart = shape.Chart;
            chart.Series.Clear();

            //Specify chart data
            string[] categories = new[] { "QTR1", "QTR2", "QTR3", "QTR4"};
            double[] values1 = new double[] { 190000, 85000, 210000, 60000};
            double[] values2 = new double[] { 230000, 100000, 250000, 120000 };

            //Add data series to the chart
            chart.Series.Add("ASIA SALES 2009", categories, values1);
            chart.Series.Add("ASIA SALES 2010", categories, values2);

            //Set chart title
            chart.Title.Text = "ASIA SALES";
            //Set the number format of the Y-axis tick labels to group digits with commas
            chart.AxisY.NumberFormat.FormatCode = "#,##0";

            //Save the result document
            document.SaveToFile("ColumnChart.docx", FileFormat.Docx2013);
            document.Dispose();
        }
    }
}

Create a 3D Surface Chart in Word in C# and VB.NET

A 3D surface chart is used to show how data is distributed over a surface. It is a type of chart that uses shading and color to represent values. To create a 3D surface chart in Word using C# or VB.NET, you can use the following code:

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

namespace Create3DSurfaceCharts
{
    internal class Program
    {
        static void Main(string[] args)
        {
            //Create a word document
            Document document = new Document();

            //Create a new section
            Section section = document.AddSection();
            section.PageSetup.Margins.All = 72f;

            //Create a new paragraph and append text
            Paragraph paragraph = section.AddParagraph();
            paragraph.AppendText("3D Surface Chart");
            paragraph.ApplyStyle(BuiltinStyle.Heading1);

            //Create a new paragraph to append a 3D Surface chart shape
            paragraph = section.AddParagraph();
            ShapeObject shape = paragraph.AppendChart(ChartType.Surface3D, 300, 200);

            //Clear the default series of the chart
            Chart chart = shape.Chart;
            chart.Series.Clear();

            //Specify chart data
            string[] categories = new[] { "QTR1", "QTR2", "QTR3", "QTR4" };
            double[] values1 = new double[] { 190000, 85000, 210000, 60000};
            double[] values2 = new double[] { 230000, 100000, 250000, 120000};
            double[] values3 = new double[] { 500000, 820000, 1500000, 400000};

            //Add data series to the chart
            chart.Series.Add("ASIA SALES 2009", categories, values1);
            chart.Series.Add("ASIA SALES 2010", categories, values2);
            chart.Series.Add("ASIA SALES 2011", categories, values3);

            //Set chart title
            chart.Title.Text = "ASIA SALES";

            //Save the result document
            document.SaveToFile("3DSurfaceChart.docx", FileFormat.Docx2013);
            document.Dispose();
        }
    }
