How to create a line chart in Word document using Word library?
Line chart created using the Word library (Essential DocIO)
Steps to create line 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.Line enum value.
//Create and Append chart to the paragraph. WChart chart = paragraph.AppendChart(446, 270); //Set chart type. chart.ChartType = OfficeChartType.Line;
- Assign data and chart elements
Add the basic elements like chart title, data labels, and legend.
- ChartTitle of the chart object.
- Set DataLabels using the DefaultDataPoint.
- Add CategoryLabels and Values.
- Set TRUE to the chart’s HasLegend property to show the legend, else False.
//Apply chart elements //Set chart title chart.ChartTitle = " Line Chart "; //Set legend chart.HasLegend = true; //Set Datalabels, CategoryLabels, and Values IOfficeChartSerie series1 = chart.Series.Add("Joey"); series1.Values = chart.ChartData[2, 2, 6, 2]; series1.SerieType = OfficeChartType.Line; IOfficeChartSerie series2 = chart.Series.Add("Mathew"); series2.Values = chart.ChartData[2, 3, 6, 3]; series2.SerieType = OfficeChartType.Line; IOfficeChartSerie series3 = chart.Series.Add("Peter"); series3.Values = chart.ChartData[2, 4, 6, 4]; series3.SerieType = OfficeChartType.Line;
The following C# and VB.NET complete code sample shows the creation of line chart using the Word library.
C#
using Syncfusion.DocIO.DLS; using Syncfusion.OfficeChart; namespace Create_Line_Chart { class Program { static void Main(string[] args) { //Load the template document. WordDocument document = new WordDocument(); // Add a section to the document. IWSection sec = document.AddSection(); //Add a paragraph to the section. IWParagraph paragraph = sec.AddParagraph(); //Create and append the chart to the paragraph. WChart chart = paragraph.AppendChart(446, 270); chart.ChartType = OfficeChartType.Line; //Assign data AddChartData(chart); chart.IsSeriesInRows = false; //Apply chart elements //Set chart title chart.ChartTitle = "Line Chart"; //Set Datalabels IOfficeChartSerie series1 = chart.Series.Add("Joey"); series1.Values = chart.ChartData[2, 2, 6, 2]; series1.SerieType = OfficeChartType.Line; IOfficeChartSerie series2 = chart.Series.Add("Mathew"); series2.Values = chart.ChartData[2, 3, 6, 3]; series2.SerieType = OfficeChartType.Line; IOfficeChartSerie series3 = chart.Series.Add("Peter"); series3.Values = chart.ChartData[2, 4, 6, 4]; series3.SerieType = OfficeChartType.Line; //Set legend chart.HasLegend = true; chart.Legend.Position = OfficeLegendPosition.Bottom; //Save and close the Word document document.Save("Output.docx"); document.Close(); } /// <summary> /// Set the values for the chart /// </summary> private static void AddChartData(WChart chart) { chart.ChartData.SetValue(1, 1, "Fruits"); chart.ChartData.SetValue(1, 2, "Joey"); chart.ChartData.SetValue(1, 3, "Mathew"); chart.ChartData.SetValue(1, 4, "Peter"); chart.ChartData.SetValue(2, 1, "Apples"); chart.ChartData.SetValue(2, 2, 5); chart.ChartData.SetValue(2, 3, 3); chart.ChartData.SetValue(2, 4, 2); chart.ChartData.SetValue(3, 1, "Grapes"); chart.ChartData.SetValue(3, 2, 4); chart.ChartData.SetValue(3, 3, 5); chart.ChartData.SetValue(3, 4, 2); chart.ChartData.SetValue(4, 1, "Bananas"); chart.ChartData.SetValue(4, 2, 4); chart.ChartData.SetValue(4, 3, 4); chart.ChartData.SetValue(4, 4, 3); chart.ChartData.SetValue(5, 1, "Oranges"); chart.ChartData.SetValue(5, 2, 2); chart.ChartData.SetValue(5, 3, 1); chart.ChartData.SetValue(5, 4, 5); chart.ChartData.SetValue(6, 1, "Melons"); chart.ChartData.SetValue(6, 2, 2); chart.ChartData.SetValue(6, 3, 7); chart.ChartData.SetValue(6, 4, 6); } } }
