How to: Export a Chart to PDF

• Nov 13, 2018

This topic explains how to export chart content to a file and to a stream in the PDF format.

1. Use the DevExpress Printing Library to export the chart. Add references to the following assemblies:

   • DevExpress.XtraPrinting.19.1
   • DevExpress.Printing.v19.1.Core

2. Use the ChartControl.IsPrintingAvailable property to check whether the chart can be exported.

3. Call the ChartControl.ExportToPdf method to export the chart.

C#

using System.IO;
using DevExpress.XtraCharts;
// ...

private void OnButtonClick(object sender, EventArgs e) {
    if(chartControl1.IsPrintingAvailable) {
        // Exports the chart in the vector-based format to a PDF file.
        chartControl1.OptionsPrint.ImageFormat = DevExpress.XtraCharts.Printing.PrintImageFormat.Metafile;
        chartControl1.ExportToPdf("D://Output1.pdf", new DevExpress.XtraPrinting.PdfExportOptions { ConvertImagesToJpeg = false });

        // Exports to a stream as PDF.
        FileStream pdfStream = new FileStream("D://Output2.pdf", FileMode.Create);
        chartControl1.ExportToPdf(pdfStream);
        // ...
        pdfStream.Close();
    }
}

VB.NET

Imports System.IO
Imports DevExpress.XtraCharts
' ...

Private Sub OnButtonClick(ByVal sender As Object, ByVal e As EventArgs)
    If chartControl1.IsPrintingAvailable Then
        ' Exports to a PDF file.
        chartControl1.OptionsPrint.ImageFormat = DevExpress.XtraCharts.Printing.PrintImageFormat.Metafile
        chartControl1.ExportToPdf("D://Output1.pdf", New DevExpress.XtraPrinting.PdfExportOptions With {
            .ConvertImagesToJpeg = False
        })
        ' Exports to a stream as PDF.
        Dim pdfStream As FileStream = New FileStream("D://Output2.pdf", FileMode.Create)
        chartControl1.ExportToPdf(pdfStream)
        ' ...
        pdfStream.Close()
    End If
End Sub
