Contour Surface chart in Word document

Steps to create contour surface chart in Word document:

Step 1: Initialize chart

Create a chart object by calling the paragraph.AppendChart(446,270) method.

//Create and append the chart to the paragraph.
WChart chart = paragraph.AppendChart(446, 270);

Step 2: Assign data, chart type and chart elements

Add the basic elements like the chart title, data labels, legend and specify the chart type to the OfficeChartType.Surface_Contour enum value.

Assign data.
Chart type.
ChartTitle of the chart object.
Set TRUE to the chart’s HasLegend property to show the legend, else False.
Note:
1. To plot the series values in column and categories in row, set chart’s IsSeriesInRows property to false.
2. Set the data range before specifying the chart type.

//Set region of Chart data.
chart.DataRange = chart.ChartData[1, 1, 7, 4];
 
//Set chart type.
chart.ChartType = OfficeChartType.Surface_Contour;
 
//Set a chart title.
chart.ChartTitle = "Contour Surface Chart";
 
//Set legend.
chart.HasLegend = true;
chart.Legend.Position = OfficeLegendPosition.Bottom;

Note:

For creating a contour surface chart, the series count must be greater than or equal to 2. The series should be set before selecting the chart type.

The following C# code sample shows the creation of contour surface 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, "Course");
    chart.ChartData.SetValue(2, 1, "English");
    chart.ChartData.SetValue(3, 1, "Physics");
    chart.ChartData.SetValue(4, 1, "Maths");
    chart.ChartData.SetValue(5, 1, "History");
    chart.ChartData.SetValue(6, 1, "Language 1");
    chart.ChartData.SetValue(7, 1, "Language 2");
    chart.ChartData.SetValue(1, 2, "SchoolA");
    chart.ChartData.SetValue(2, 2, 63);
    chart.ChartData.SetValue(3, 2, 61);
    chart.ChartData.SetValue(4, 2, 62);
    chart.ChartData.SetValue(5, 2, 46);
    chart.ChartData.SetValue(6, 2, 60);
    chart.ChartData.SetValue(7, 2, 63);
    chart.ChartData.SetValue(1, 3, "SchoolB");
    chart.ChartData.SetValue(2, 3, 53);
    chart.ChartData.SetValue(3, 3, 55);
    chart.ChartData.SetValue(4, 3, 51);
    chart.ChartData.SetValue(5, 3, 53);
    chart.ChartData.SetValue(6, 3, 56);
    chart.ChartData.SetValue(7, 3, 58);
    chart.ChartData.SetValue(1, 4, "SchoolC");
    chart.ChartData.SetValue(2, 4, 45);
    chart.ChartData.SetValue(3, 4, 65);
    chart.ChartData.SetValue(4, 4, 64);
    chart.ChartData.SetValue(5, 4, 66);
    chart.ChartData.SetValue(6, 4, 64);
    chart.ChartData.SetValue(7, 4, 64);
    //Set region of Chart data.
    chart.DataRange = chart.ChartData[1, 1, 7, 4];
    //Set chart type.
    chart.ChartType = OfficeChartType.Surface_Contour;
    //Set chart series in the column for assigned data region.
    chart.IsSeriesInRows = false;
    //Set a Chart Title.
    chart.ChartTitle = "Contour Surface Chart";
    //Set legend.
    chart.HasLegend = true;
    chart.Legend.Position = OfficeLegendPosition.Bottom;
    //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);
